Evaluate and support airway, breathing, and circulation. Children may be more vulnerable to corrosive agents than adults because of the smaller diameter of their airways. In cases of respiratory compromise secure airway and respiration via endotracheal intubation. If not possible, surgically secure an airway.
Irrigate exposed or irritated eyes with saline, Ringer's lactate, or D5W for at least 20 minutes. Eye irrigation may be carried out simultaneously with other basic care and transport. Remove contact lenses if it can be done without additional trauma to the eye. If a corrosive material is suspected or if pain or injury is evident, continue irrigation while transferring the victim to the support zone.

Rapid decontamination is critical. Victims who are able may assist with their own decontamination. Remove and double-bag contaminated clothing and personal belongings.
This handout provides information and follow-up instructions for persons who have been exposed to calcium or sodium hypochlorite.
Consider racemic epinephrine aerosol for children who develop stridor. Dose 0.25-0.75 mL of 2.25% racemic epinephrine solution in water, repeat every 20 minutes as needed cautioning for myocardial variability.
Consult with the base station physician or the regional poison control center for advice regarding triage of multiple victims.
Patients who have ingested hypochlorite, or who show evidence of significant exposure to hypochlorite or chlorine (e.g., severe or persistent cough, dyspnea or chemical burns) should be transported to a medical facility for evaluation. Patients who have minor or transient irritation of the eyes or throat may be discharged from the scene after their names, addresses, and telephone numbers are recorded. They should be advised to seek medical care promptly if symptoms develop or recur (see Patient Information Sheet below).
Flush exposed skin and hair with copious amounts of plain tepid water. Use caution to avoid hypothermia when decontaminating victims, particularly children or the elderly. Use blankets or warmers after decontamination as needed.
[ ] Avoid drinking alcoholic beverages for at least 24 hours; alcohol may worsen injury to your stomach or have other effects.
Other persons may still be at risk in the setting where this incident occurred. If the incident occurred in the workplace, discussing it with company personnel may prevent future incidents. If a public health risk exists, notify your state or local health department or other responsible public agency. When appropriate, inform patients that they may request an evaluation of their workplace from OSHA or NIOSH. See Appendix III for a list of agencies that may be of assistance.
Because of their relatively larger surface area:body weight ratio children are more vulnerable to toxicants that affect the skin.
Sodium hypochloritecommon name
Synonyms of sodium hypochlorite include Clorox, bleach, liquid bleach, sodium oxychloride, Javex, antiformin, showchlon, chlorox, B-K, Carrel-dakin solution, Chloros, Dakin's solution, hychlorite, Javelle water, Mera Industries 2MOm³B, Milton, modified dakin's solution, Piochlor, and 13% active chlorine.
Be certain that victims have been decontaminated properly (see Decontamination Zone above). Victims who have undergone decontamination or have been exposed only to vapor pose no serious risks of secondary contamination to rescuers. In such cases, Support Zone personnel require no specialized protective gear.
Consider racemic epinephrine aerosol for children who develop stridor. Dose 0.25-0.75 mL of 2.25% racemic epinephrine solution in water, repeat every 20 minutes as needed cautioning for myocardial variability.
V-Gard™ Hearing Protection Ear Muffs with Helmet Mounted Adapter, Type 14 delivers enhanced comfort and top of the line performance with upgrades in fit and style, all without compromising quality.
Be aware that use of protective equipment by the provider may cause anxiety, particularly in children, resulting in decreased compliance with further management efforts.
Patients who ingested large volumes of hypochlorite, who have unreliable histories, or are symptomatic complaining of pain in swallowing, persistent shortness of breath, severe cough, or chest tightness should be admitted to the hospital and observed until symptom-free. Injury may progress for several hours.
More information about hypochlorite can be obtained from your regional poison control center, your state, county, or local health department; the Agency for Toxic Substances and Disease Registry (ATSDR); your doctor; or a clinic in your area that specializes in occupational and environmental health. If the exposure happened at work, you may wish to discuss it with your employer, the Occupational Safety and Health Administration (OSHA), or the National Institute for Occupational Safety and Health (NIOSH). Ask the person who gave you this form for help in locating these telephone numbers.
Follow up is recommended for all hospitalized patients because long-term gastrointestinal or respiratory problems can result. Respiratory monitoring is recommended until the patient is symptom-free. Chlorine-induced reactive airways dysfunction syndrome (RADS) has been reported to persist from 2 to 12 years.
Victims who are conscious and able to swallow should be given 4 to 8 ounces of water or milk; if the victim is symptomatic, delay decontamination until other emergency measures have been instituted. Dilutants are contraindicated in the presence of shock, upper airway obstruction, or in the presence of perforation.
Children may be more vulnerable to corrosive agents than adults because of the smaller diameter of their airways. Children may also be more vulnerable to gas exposure because of increased minute ventilation per kg and failure to evacuate an area promptly when exposed.
Rescuers should be trained and appropriately attired before entering the Hot Zone. If the proper equipment is not available, or if rescuers have not been trained in its use, assistance should be obtained from a local or regional HAZMAT team or other properly equipped response organization.
Evaluate and support airway, breathing, and circulation as in ABC Reminders above. Children may be more vulnerable to corrosive agents than adults because of the smaller diameter of their airways. Establish intravenous access in seriously ill patients if this has not been done previously. Continuously monitor cardiac rhythm.
Administer supplemental oxygen by mask to patients who have respiratory symptoms. Treat patients who have bronchospasm with an aerosolized bronchodilator such as albuterol.
There is no antidote for hypochlorite, but its effects can be treated and most exposed persons get well. Persons who have experienced serious symptoms may need to be hospitalized.
Sodium hypochloritesolution
Ingestion of hypochlorite solutions or powder can also cause severe corrosive injury to the mouth, throat, esophagus, and stomach, with bleeding, perforation, scarring, or stricture formation as potential sequelae.
Ingestion of hypochlorite solutions may lead to pulmonary complications when the liquid is aspirated. Inhalation of gases released from hypochlorite solutions may cause eye and nasal irritation, sore throat, and coughing at low concentrations. Inhalation of higher concentrations can lead to respiratory distress with airway constriction and accumulation of fluid in the lungs (pulmonary edema). Patients may exhibit immediate onset of rapid breathing, cyanosis, wheezing, rales, or hemoptysis. Pulmonary injury may occur after a latent period of 5 minutes to 15 hours and can lead to reactive airways dysfunction syndrome (RADS), a chemical irritant-induced type of asthma.
Quickly establish a patent airway, ensure adequate respiration and pulse. Stabilize the cervical spine with a collar and a backboard if trauma is suspected. Administer supplemental oxygen as required. Assist ventilation with a bag-valve-mask device if necessary.
Children do not always respond to chemicals in the same way that adults do. Different protocols for managing their care may be needed.
Sodium hypochloriteformula
Direct contact with hypochlorite solutions, powder, or concentrated vapor causes severe chemical burns, leading to cell death and ulceration.
If a chemical has been ingested, prepare the ambulance in case the victim vomits toxic material. Have ready several towels and open plastic bags to quickly clean up and isolate vomitus.
Hypochlorite irritates the skin and can cause burning pain, inflammation, and blisters. Damage may be more severe than is apparent on initial observation and can continue to develop over time.
Exposure to toxic gases generated from hypochlorite solutions can lead to reactive airways dysfunction syndrome (RADS), a chemical irritant-induced type of asthma. Chronic complications following ingestion of hypochlorite include esophageal obstruction, pyloric stenosis, squamous cell carcinoma of the esophagus, and vocal cord paralysis with consequent airway obstruction.
Keep this page and take it with you to your next appointment. Follow only the instructions checked below.
Irrigate exposed or irritated eyes with saline, Ringer's lactate, or D5W for at least 20 minutes. Remove contact lenses if it can be done without additional trauma to the eye. Continue irrigation while transporting the patient to the Critical Care Area.
Consider hospitalizing patients who have a suspected significant exposure or have eye burns or serious skin burns. Patients with perforation should be prepared for emergency surgery.
Hypochlorite powder, solutions, and vapor are irritating and corrosive. Swallowing hypochlorite or contact with the skin or eyes produces injury to any exposed tissues. Exposure to gases released from hypochlorite may cause burning of the eyes, nose, and throat; cough; and damage to the airway and lungs. Generally, the more serious the exposure, the more severe the symptoms.
Be certain that appropriate decontamination has been carried out (see Decontamination Area above).
Respiratory Protection: Positive-pressure, self-contained breathing apparatus (SCBA) is recommended in response to situations that involve exposure to potentially unsafe levels of chlorine gas.
Contact with low concentrations of household bleach causes mild and transitory irritation if the eyes are rinsed, but effects are more severe and recovery is delayed if the eyes are not rinsed. Exposure to solid hypochlorite or concentrated solutions can produce severe eye injuries with necrosis and chemosis of the cornea, clouding of the cornea, iritis, cataract formation, or severe retinitis.
Optime™ Ear Muffs provide maximum sound quality in the most demanding environments where noise exposures are expected to reach as high as 105 dBA.
The diagnosis of acute hypochlorite toxicity is primarily clinical. However, laboratory testing is useful for monitoring the patient and evaluating complications. Routine laboratory studies for all exposed patients include CBC, glucose, and electrolyte determinations. Patients who have respiratory complaints may require pulse oximetry (or ABG measurements) and chest radiography. Chlorine inhalation may be complicated by hyperchloremic metabolic acidosis; in addition to electrolytes, monitor blood pH.
Pharyngeal pain is the most common symptom after ingestion of hypochlorite, but in some cases (particularly in children), significant esophagogastric injury may not have oral involvement. Additional symptoms include dysphagia, stridor, drooling, odynophagia, and vomiting. Pain in the chest or abdomen generally indicates more severe tissue damage. Respiratory distress and shock may be present if severe tissue damage has already occurred. In children, refusal to take food or drink liquid may represent odynophagia.
When you call for your appointment, please say that you were treated in the Emergency Department at _________ Hospital by________and were advised to be seen again in ____days.

Give 4 to 8 ounces of water or milk to alert patients who can swallow if not done previously. Dilutants are contraindicated in the presence of shock, upper airway obstruction, or in the presence of perforation.
Optime™ 98 is versatile ear muff featuring a stainless steel headband and is recommended for TWA noise exposures up to 98 dBA.
Specific tests for the presence of hypochlorite in blood or urine generally are not useful to the doctor. If a severe exposure has occurred, blood and urine analyses and other tests may show whether the lungs, heart, or brain have been injured. Testing is not needed in every case.
Calcium hypochlorite is generally available as a white powder, pellets, or flat plates. It decomposes readily in water or when heated, releasing oxygen and chlorine. It has a strong chlorine odor, but odor may not provide an adequate warning of hazardous concentrations. Calcium hypochlorite is not flammable, but it acts as an oxidizer with combustible material and may react explosively with ammonia, amines, or organic sulfides. Calcium hypochlorite should be stored in a dry, well ventilated area at a temperature below 120ºF (50ºC) separated from acids, ammonia, amines, and other chlorinating or oxidizing agents.
Calcium or sodium hypochlorite react explosively or form explosive compounds with many common substances such as ammonia, amines, charcoal, or organic sulfides
Consider appropriate management of chemically contaminated children at the exposure site. Provide reassurance to the child during decontamination, especially if separation from a parent occurs.
PELTOR™ X5 Series Ear Muffs feature a combination of specially-formulated foam plus an innovative spacer and cup design to make it ideal for very high level noise situations.
The toxic effects of sodium and calcium hypochlorite are primarily due to the corrosive properties of the hypochlorite moiety. Hypochlorite causes tissue damage by liquefaction necrosis. Fats and proteins are saponified, resulting in deep tissue destruction. Further injury is caused by thrombosis of blood vessels. Injury increases with hypochlorite concentration and pH. Symptoms may be apparent immediately or delayed for a few hours. Calcium hypochlorite decomposes in water releasing chlorine gas. Sodium hypochlorite solutions liberate the toxic gases chlorine or chloramine if mixed with acid or ammonia (this can occur when bleach is mixed with another cleaning product). Thus, exposure to hypochlorite may involve exposure to these gases.
Victims who are conscious and able to swallow should be given 4 to 8 ounces of water or milk; if the victim is symptomatic, delay decontamination until other emergency measures have been instituted. Dilutants are contraindicated in the presence of shock, upper airway obstruction, or in the presence of perforation.
[ ] Call your doctor or the Emergency Department if you develop any unusual signs or symptoms within the next 24 hours, especially:
Asymptomatic patients and those who experienced only minor irritation of the nose, throat, eyes, or respiratory tract may be released. In most cases, these patients will be free of symptoms in an hour or less. They should be advised to seek medical care promptly if symptoms develop or recur (see the Hypochlorite--Patient Information Sheet below).
Contraindications for endoscopy include: unstable patient, evidence of perforation, upper airway compromise, or more than 48 hours after ingestion.
If you have questions or concerns, please contact your community or state health or environmental quality department or:
Quickly establish a patent airway, ensure adequate respiration and pulse. If trauma is suspected, maintain cervical immobilization manually and apply a cervical collar and a backboard when feasible. Administer supplemental oxygen as required and establish intravenous access if necessary. Place on a cardiac monitor, if available.

Patients who are able may assist with their own decontamination. Remove and double bag contaminated clothing and personal belongings.
Unless previously decontaminated, all patients suspected of contact with hypochlorite and all victims with skin or eye irritation require decontamination as described below. Patients exposed only to chlorine gas who have no skin or eye irritation may be transferred immediately to the Critical Care Area. Because hypochlorite is an irritant, don butyl rubber gloves and apron before treating patients.
Radians Lowset™ 21 Earmuffs have foam filled, cushion padding on earcups along with evenly spread tension in the headband to allow for comfortable wear while wearing protective safety glasses
Children exposed to the same levels of gases as adults may receive a larger dose because they have greater lung surface area:body weight ratios and higher minute volumes:weight ratios. Children may be more vulnerable to corrosive agents than adults because of the smaller diameter of their airways. In addition, they may be exposed to higher levels than adults in the same location because of their short stature and the higher levels of chlorine found nearer to the ground.
Sodium hypochloritevs bleach
Quickly establish a patent airway, ensure adequate respiration and pulse. If trauma is suspected, maintain cervical immobilization manually and apply a cervical collar and a backboard when feasible.
Only decontaminated patients or those not requiring decontamination should be transported to a medical facility. "Body bags" are not recommended.
Consider racemic epinephrine aerosol for children who develop stridor. Dose 0.25-0.75 mL of 2.25% racemic epinephrine solution in water, repeat every 20 minutes as needed cautioning for myocardial variability.
In cases of respiratory compromise secure airway and respiration via endotracheal intubation. Avoid blind nasotracheal intubation or use of an esophageal obturator: only use direct visualization to intubate. When the patient's condition precludes endotracheal intubation, perform cricothyrotomy if equipped and trained to do so.
If concentrated hypochlorite solutions contact the skin, chemical burns may occur; treat as thermal burns. Patients developing dermal hypersensitivity reactions may require treatment with systemic or topical corticosteroids or antihistamines.

A single small exposure from which a person recovers quickly is not likely to cause delayed or long-term effects. After a serious exposure, symptoms may worsen for several hours.
Synonyms of calcium hypochlorite include Losantin, hypochlorous acid, calcium salt, BK powder, Hy-Chlor, chlorinated lime, lime chloride, chloride of lime, calcium oxychloride, HTH, mildew remover X-14, perchloron, and pittchlor.
Irrigate exposed or irritated eyes with saline, Ringer's lactate, or D5W for at least 20 minutes. Check the pH of the conjunctiva every 30 minutes for 2 hours after irrigation is stopped. If the pH is not neutral an irrigating contact lens should be used to apply continuous irrigation for several hours until the pH of the tissue normalizes. Test visual acuity and examine the eyes for corneal damage and treat appropriately. Immediately consult an ophthalmologist for patients who have corneal injuries.
Direct visualization of the esophagus is of primary importance for determining the extent of injury. All patients who are suspected of having significant ingestion, or those (such as children) for whom there is an unreliable history, must have early endoscopy within 36 to 48 hours of ingestion. Use of a flexible endoscope is associated with a lower risk of perforation. The esophagus, stomach and duodenum should be endoscopically evaluated because burns of the esophagus do not correlate with the presence of burns in the stomach.
No information was located regarding reproductive or developmental effects of calcium or sodium hypochlorite in experimental animals or humans. Calcium and sodium hypochlorite are not included in Reproductive and Developmental Toxicants, a 1991 report published by the U.S. General Accounting Office (GAO) that lists 30 chemicals of concern because of widely acknowledged reproductive and developmental consequences.
Obtain the name of the patient's primary care physician so that the hospital can send a copy of the ED visit to the patient's doctor.
Ingestion of hypochlorite solutions causes vomiting and corrosive injury to the gastrointestinal tract. Household bleaches (3 to 6% sodium hypochlorite) usually cause esophageal irritation, but rarely cause strictures or serious injury such as perforation. Commercial bleaches may contain higher concentrations of sodium hypochlorite and are more likely to cause serious injury. Metabolic acidosis is rare, but has been reported following the ingestion of household bleach. Pulmonary complications resulting from aspiration may also be seen after ingestion.
Calcium hypochlorite is generally available as a white powder, pellets, or flat plates, while sodium hypochlorite is usually a greenish yellow, aqueous solution. Hypochlorite is used widely in cleaning agents, and in bleaching, drinking-water and swimming-pool disinfecting. Calcium hypochlorite decomposes in water to release chlorine and sodium hypochlorite solutions and can release chlorine gas if mixed with other cleaning agents.
PELTOR™ X Series Forestry Ear Muffs are electrically insulated with orange coloring to improve visibility for use in the forestry and other applicable industries.
Victims exposed only to chlorine gas released by hypochlorite who have no skin or eye irritation do not need decontamination. They may be transferred immediately to the Support Zone. All others require decontamination as described below.
Because of their relatively larger surface area:body weight ratio, children are more vulnerable to toxins affecting the skin.

Consider appropriate management in victims with chemically-induced acute disorders, especially children who may suffer separation anxiety if separated from a parent or other adult.
Patients who are comatose, hypotensive, or having seizures or cardiac arrhythmias should be treated in the conventional manner.
The International Agency for Research on Cancer has determined that hypochlorite salts are not classifiable as to their carcinogenicity to humans.
If a work-related incident has occurred, you may be legally required to file a report; contact your state or local health department.
If exposure levels are determined to be safe, decontamination may be conducted by personnel wearing a lower level of protection than that worn in the Hot Zone (described above).
Patients who are comatose, hypotensive, or having seizures or who have cardiac arrhythmias should be treated according to advanced life support (ALS) protocols.
Skin Protection: Chemical-protective clothing should be worn due to the risk of skin irritation and burns from direct contact with solid hypochlorite or concentrated solutions.
Because of their relatively larger surface area:weight ratio, children are more vulnerable to toxicants affecting the skin. Also, emergency department personnel should examine children's mouths because of the frequency of hand-to-mouth activity among children.
Sodium hypochlorite is generally sold in aqueous solutions containing 5 to 15% sodium hypochlorite, with 0.25 to 0.35% free alkali (usually NaOH) and 0.5 to 1.5% NaCl. Solutions of up to 40% sodium hypochlorite are available, but solid sodium hypochlorite is not commercially used. Sodium hypochlorite solutions are a clear, greenish yellow liquid with an odor of chlorine. Odor may not provide an adequate warning of hazardous concentrations. Sodium hypochlorite solutions can liberate dangerous amounts of chlorine or chloramine if mixed with acids or ammonia. Anhydrous sodium hypochlorite is very explosive. Hypochlorite solutions should be stored at a temperature not exceeding 20ºC away from acids in well-fitted air-tight bottles away from sunlight.
Hypochlorite solutions can liberate toxic gases such as chlorine. Chlorine's odor or irritant properties generally provide adequate warning of hazardous concentrations. However, prolonged, low-level exposures, such as those that occur in the workplace, can lead to olfactory fatigue and tolerance of chlorine's irritant effects. Chlorine is heavier than air and may cause asphyxiation in poorly ventilated, enclosed, or low-lying areas.
Sodium hypochloriteuses
Flush exposed skin and hair with copious amounts of plain water. Use caution to avoid hypothermia when decontaminating victims, particularly children or the elderly. Use blankets or warmers after decontamination as needed.
PELTOR™ X4 Series Ear Muffs combines high attenuation with a sleek, low-profile and lightweight design. Available in over-the-head or hard hat-attached styles.
Because of their relatively larger surface area:weight ratio, children are more vulnerable to toxicants affecting the skin.
Victims who are conscious and able to swallow should be given 4 to 8 ounces of water or milk. Dilutants are contraindicated in the presence of shock, upper airway obstruction, or in the presence of perforation.
Sodium and calcium hypochlorite are manufactured by the chlorination of sodium hydroxide or lime. Sodium and calcium hypochlorite are used primarily as oxidizing and bleaching agents or disinfectants. They are components of commercial bleaches, cleaning solutions, and disinfectants for drinking water and waste water purification systems and swimming pools (Teitelbaum 2001).
Patients who are comatose, hypotensive, or having seizures or cardiac arrhythmias should be treated in the conventional manner.
If victims can walk, lead them out of the Hot Zone to the Decontamination Zone. Victims who are unable to walk may be removed on backboards or gurneys; if these are not available, carefully carry or drag victims to safety.
Report to the base station and the receiving medical facility the condition of the patient, treatment given, and estimated time of arrival at the medical facility.
