The presence of hydrogen chloride in the environment does not always lead to exposure. In order for it to cause any adverse health effects you must come into contact with it. You may be exposed to hydrogen chloride by breathing it. You may be exposed to hydrochloric acid by drinking it, or by contact with your skin or eyes. Following exposure to any chemical, the adverse health effects you may encounter depend on several factors, including the amount to which you are exposed (dose), the way you are exposed, the duration of exposure, the form of the chemical and if you were exposed to any other chemicals.

Due to hydrogen chloride being used in a number of industrial settings, occupational exposure is more common. Exposure mainly occurs through malfunctions or accidental releases. However, safe limits are enforced to protect the employees; such levels are below those that are thought to cause harmful effects.

Strong solutions of hydrochloric acid are highly corrosive and can cause skin burns on contact; they may also damage the eyes. Dilute solutions may cause irritation to the eyes and skin. Drinking hydrochloric acid will burn the mouth, throat and stomach.

Hydrogen chloride has many industrial uses such as cleaning, pickling and electroplating metals, tanning leather, refining soap as well as for making vinyl chloride, fertilizers, artificial silk, dyes and pigments for paint. It is also used in the photographic, textile and rubber industry. It may be found as an ingredient in some cleaning products available in the UK.

Officers take reasonable steps to balance the privacy rights of individuals with the benefits of using body-worn cameras for law enforcement purposes. Recording under certain circumstances will depend on the lawful authority of the officer’s presence.

There is little evidence on the effects of exposure to hydrogen chloride during pregnancy. Therefore, is not possible to draw any definitive conclusions. Effects on the unborn child are more likely to occur at levels that harm the mother.

Exposure to hydrogen chloride may occur following contact with cleaning products that contain it; however, exposure is likely to be minimal if the products are used appropriately.

Officers are trained to give notice of the camera’s operation as soon as reasonably possible. The timing of this notice may vary depending on the context and safety of the encounter. To signal its activation, the camera will emit three audible sounds, and flash red.

If you have hydrogen chloride in your eyes, remove contact lenses, irrigate the affected eye with lukewarm water for at least 10 to 15 minutes and seek medical advice. If you have inhaled or ingested hydrogen chloride, seek medical advice.

Children are likely to be affected by hydrogen chloride in the same way as adults. Hydrochloric acid containing products in the home should be stored in an appropriate container and kept out of the reach of children.

Hydrogen chloride, in the form of hydrochloric acid, may be added to water supplies or swimming pools to change the pH and prevent scale formation. Its use in swimming pools is tightly controlled and due to the acid being neutralised, does not present a health hazard.

Hydrogen chloride is formed by human activities such as from coal-burning power stations and incinerators. Burning of fossil fuels produces hydrogen chloride, although the use of these fuels is decreasing so will be a minor source of hydrogen chloride emissions in the future. Hydrogen chloride is also formed in large quantities when materials such as plastics or polyvinyl chloride (PVC) are burnt. Volcanoes also produce hydrogen chloride.

At room temperature, hydrogen chloride exists as either a colourless or slightly yellow gas. It is heavier than air and has a strong pungent odour. Hydrogen chloride will dissolve in water to form hydrochloric acid.

In March 2022, the Saskatoon Police Service implemented the BWC program, deploying 40 cameras to front-line officers in the Patrol, Traffic, Foot Patrol, Bike and Community Mobilization Units, and Alternative Response Officers. The audio and video recording device will document police and civilian interactions while engaged in enforcement and investigative duties. This includes but is not limited to calls for service, including mental health, traffic stops, and contact interviews. BWC’s are intended to support law enforcement duties and aid in capturing certain incidents. They are not intended for continuous recording. BWC’s are openly displayed to the public and will show an illuminated red LED light notifying the public when the camera is recording.

The element of video has evolved rapidly over the past few years, becoming an integral part of our society. It has also affected policing in the many different ways it is utilized; from home security systems and cell phone recordings to in-car cameras, the use of video is common and can be an important investigative tool. It also provides a new level of accountability and transparency. This has been proven with law enforcement agencies across the globe adopting body-worn cameras (BWC).

Low levels of naturally occurring hydrogen chloride may be breathed in from air. A lot of naturally occurring hydrogen chloride is removed by rain, which reduces levels in the air.

Asthmatics or individuals with other breathing problems may be more sensitive to the effect of hydrogen chloride on the airways.

“Body-worn cameras can’t replace an officer’s perceptions, but they can be extraordinarily valuable when they confirm the presence of weapons, capture resistance, and verify de-escalation attempts. What’s more, it is expected that the presence of cameras encourages people on both sides of the lens to be the best version of themselves as they interact.”

Breathing in low levels of hydrogen chloride for a short period of time can cause irritation to the nose and throat, causing coughing and shortness of breath. Exposure to higher concentrations of hydrogen chloride can also cause headache, fever wheeze, a rapid heart rate and confusion. In serious cases the airways may be damaged and a condition called pulmonary oedema where fluid builds up in the lungs, may develop. Following severe injuries from inhaling hydrogen chloride, there may be lasting effect on the lungs and airways. Hydrogen chloride gas is not absorbed through the skin but when it comes into contact with moisture (such a sweat), it forms hydrochloric acid which is highly irritating and corrosive.

SPS officers must balance the privacy rights of individuals with the anticipated benefits of using BWC’s for law enforcement purposes. The program and policy is will be evaluated on an ongoing basis to ensure its compliance with the Canadian Charter of Rights and Freedoms, the Criminal Code of Canada and provincial legislation. Recording in a private place is dependent on the lawful authority of an officer’s attendance at the location. Some examples include receiving consent from the owner/occupant, in relation to a search warrant or exigent/extenuating circumstances.

If you have got hydrogen chloride on your skin, remove soiled clothing (not over the head), wash the affected area with lukewarm water and soap for at least 10 to 15 minutes and seek medical advice.

Officers are trained to be aware of interactions with the public that may be sensitive in nature, such as when children are present, during a sexual assault or domestic violence investigation. Additionally, a video management team is responsible for the removal/redaction of privileged, sensitive or clearly irrelevant content prior to the disclosure or release of a copy of a BWC recording.

Where we have identified any third party copyright information you will need to obtain permission from the copyright holders concerned.

Recordings cannot be edited, altered, or deleted from the camera by a police officer. The video management team has access and permissions to search and view BWC recordings for the purposes of preparing redacted copies for court disclosure purposes and FOIP requests. They are responsible for the removal or redaction of privileged, sensitive or clearly irrelevant content prior to the disclosure or release of a copy of a BWC recording. An unedited version of the recording will be saved and will remain accessible (until retention policies dictate its deletion).

During incidents including but not limited to calls for service, including those related to mental health, traffic stops, and contact interviews. Camera’s will be activated upon arriving at an incident and will continue to record until the incident is completed.

Unlike the United States, there are significant privacy implications in Canada governing our ability to release BWC footage to the media and/or public. In the vast majority of incidents, it is expected that recordings will not be released publicly, however, members of the public can access the video by submitting a FOIP request. Members of the public cannot request the data to be deleted; recordings are stored according to the retention policies and if disclosed for court purposes, will be redacted and vetted for any privacy-related concerns or issues.
