This symbol has also been more widely adopted for generic use in many other contexts not associated with poisonous materials. It used for denoting number of dead victims caused by natural disasters (e.g. earthquakes) or armed conflicts on event infographics.

This symbol has also been more widely adopted for generic use in many other contexts not associated with road traffic. It often appears on hazardous equipment, in instruction manuals to draw attention to a precaution, on tram/train blind spot warning stickers and on natural disaster (earthquake, tsunami, hurricane, volcanic eruption) preparedness posters/brochures—as an alternative when a more-specific warning symbol is not available.

Flammablesymbol

All parts of the biohazard sign can be drawn with a compass and straightedge. The basic outline of the symbol is a plain trefoil, which is three circles overlapping each other equally like in a triple Venn diagram with the overlapping parts erased. The diameter of the overlapping part is equal to half the radius of the three circles. Then three inner circles are drawn in with 2⁄3 radius of the original circles so that it is tangent to the outside three overlapping circles. A tiny circle in center has a diameter 1⁄2 of the radius of the three inner circles, and arcs are erased at 90°, 210°, and 330°. The arcs of the inner circles and the tiny circle are connected by a line. Finally, the ring under is drawn from the distance to the perimeter of the equilateral triangle that forms between the centers of the three intersecting circles. An outer circle of the ring under is drawn and finally enclosed with the arcs from the center of the inner circles with a shorter radius from the inner circles.[11]

Due to the shortness of the wires in the grip. I was unable to reconnect them. TASER was nice enough to send a replacement.

The biohazard symbol is used in the labeling of biological materials that carry a significant health risk, including viral and bacteriological samples, including infected dressings and used hypodermic needles (see sharps waste).[20]

In the United States, due to concerns that the skull-and-crossbones symbol's association with pirates might encourage children to play with toxic materials, the Mr. Yuk symbol is also used to denote poison.

While contact distance works, the benefit of the TASER Pulse is the fact that it has cartridges with flying barbed probes. This provides the user with a bit of a cushion of safety. You can engage a target out to 15 feet rather than have to get up close and personal. Like I said earlier, the Pulse has polymer sights but since the laser activates as soon as you switch the safety off, I ended up using the laser 100% of the time. Normally lasers do not work well in daylight but don’t forget the Pulse only has an effective range of 15 feet. It is not hard to see the laser at such a short distance.

The sign is commonly referred to as a radioactivity warning sign, but it is actually a warning sign of ionizing radiation. Ionizing radiation is a much broader category than radioactivity alone, as many non-radioactive sources also emit potentially dangerous levels of ionizing radiation. This includes x-ray apparatus, radiotherapy linear accelerators, and particle accelerators. Non-ionizing radiation can also reach potentially dangerous levels, but this warning sign is different from the trefoil ionizing radiation warning symbol.[15] The sign is not to be confused with the fallout shelter identification sign introduced by the Office of Civil Defense in 1961. This was originally intended to be the same as the radiation hazard symbol but was changed to a slightly different symbol because shelters are a place of safety, not of hazard.[10][16]

How likely would you shoot a TASER Pulse sideways? Probably not often but you will need to keep this in mind if you plan to carry one. Even though one of the probes made contact with the target, it needs the other probe to complete the circuit. So in this case, the TASER Pulse would not stop the threat. This is a perfect time and opportunity to use the contacts of the Pulse. When the probes do not make a complete circuit, the Pulse reverts to the path of least resistance. So the electricity will skip the incomplete circuit and jump across the metal contacts at the end of the Pulse pistol. You can then push the front end of the Pulse into the threat and this will complete the circuit. The Pulse becomes the second probe.

Tape with yellow and black diagonal stripes is commonly used as a generic hazard warning. This can be in the form of barricade tape, or as a self-adhesive tape for marking floor areas and the like. In some regions (for instance the UK)[5] yellow tape is buried a certain distance above buried electrical cables to warn future groundworkers of the hazard.

When shooting the Pulse like a handgun, the probes are positioned like an over under. The first probe pretty much flies straight while the second probe has a significant drop. At 15 feet, the probes spread apart about two feet. This is due to the design of the cartridges. The probes are not loaded in the cartridge parallel to each other. Rather they are positioned at an angle. The cartridges can be loaded upside down or right side up in the TASER Pulse. Which ever probe is on top, will be positioned relatively parallel with the sights. This then positions the bottom probe at a downward angle. This is what give it the spread it needs for better Neuro-Musclar Incapacitation.

Biohazard symbol

Another concern is clothing. Thick clothing can impede the probes. I went to my local Goodwill and acquired an insulated vest. I was looking for thick jackets but this will do. The first shot was shot sideways. You can see one of the probes hit the target while the other probe got stuck in the vest material. Even though the probes hit the target, one stuck into the target, the other was stopped by the vest. This prevents the electricity from affecting the target.

The Taser Pulse costs $399.99. That is the cost of many handguns. And while the Pulse works as a contact stun gun, you want the flying barbed probes. Replacement cartridges can be purchased, they come in pairs for $69.99 on Taser’s website. Of course, a handgun may not always be the right choice of tool. You might be in a place that does not allow you to carry a firearm but you could carry a TASER like the Pulse. I do have my reservations regarding its effectiveness. Recently there was a man on an American Airlines flight that seemed to be taserproof.

The international radiation symbol is a trefoil around a small central circle representing radiation from an atom. It first appeared in 1946 at the University of California, Berkeley Radiation Laboratory.[8] At the time, it was rendered as magenta, and was set on a blue background. The shade of magenta used (Martin Senour Roman Violet No. 2225) was chosen because it was expensive and less likely to be used on other signs.[9] However, a blue background for other signs started to be used extensively. Blue was typically used on information signs and the color tended to fade with weathering. This resulted in the background being changed on the radiation hazard sign.[10] The original version used in the United States is magenta against a yellow background, and it is drawn with a central circle of radius R, an internal radius of 1.5R and an external radius of 5R for the blades, which are separated from each other by 60°. The trefoil is black in the international version, which is also used in the United States.[11]

The biohazard symbol was developed in 1966 by Charles Baldwin, an environmental-health engineer working for the Dow Chemical Company on their containment products.[21]

Hazard symbols and meanings

@Nicholas C Well, of course I also have a pistol. I’m not suggesting anyone should but a taser instead. Rather, I’m suggesting that you can get them cheaper than the review makes it seem.

I do like the integrated flashlight and laser although I would prefer a staggering amount of lumens to temporarily blind your threat. I could see the TASER Pulse being an option for people who are not comfortable carrying a firearm but just like any firearm, you should seek proper training. TASER has a variety of training from self training kits to trained professionals that can teach you how to use your TASER Pulse. You can check the different levels of training on TASER’s website. You also need to check your local laws regarding the legality of using and owning a TASER. Check out the handy map below and check your local statutes as this information may not be up to date.

Second shot, this time I closed the vest and shot the Pulse vertically. The vest completely stopped the probes and did not allow them to enter the target rendering them useless.

Irritant hazard symbol

When an X26C, X26P M26C, X2, C2, Bolt or Pulse Conducted Electrical Weapon is used in self-defense, the weapons may be deployed and left behind providing the Purchaser a window of opportunity to get to safety and call law enforcement. TASER International will replace the X26C, X26P M26C, X2, C2, Bolt or Pulse weapons free of charge, with the same product or a like product, at TASER International’s option, if the Purchaser provides, within one year following the event, the following information to TASER International:

Some warning symbols have been redesigned to be more comprehensible to children, such as the Mr. Ouch (depicting an electricity danger as a snarling, spiky creature) and Mr. Yuk (a green frowny face sticking its tongue out, to represent poison) designs in the United States.

The live cartridges are kept in a clear polymer exoskeleton case. You pop them out of the case and insert them into the front of the TASER Pulse. Below you can see how the Pulse compares in size to a Glock 19X.

On the opposite end, there are two metal contact points. These contacts are what the arc of electricity jump across and what activates the cartridges. Just below the large yellow opening is an LED light and laser. Just like the plastic iron sights, the laser is not adjustable.

The US-based National Fire Protection Association (NFPA) has a standard NFPA 704 using a diamond with four colored sections each with a number indicating severity 0–4 (0 for no hazard, 4 indicates a severe hazard).[35] The system was developed in the early 1960s, as a means to warn firefighters of possible dangers posed by storage tanks filled with chemicals. The red section denotes flammability. The blue section denotes health risks. Yellow represents reactivity (tendency to explode). The white section denotes special hazard information, not properly covered by the other categories, such as water reactivity, oxidizers, and asphyxiant gases.[35]

Corrosive symbol

When you fire the TASER Cartridges, and the probes make contact with the intended target, the Pulse will continue to send electricity through the probes for 30 seconds. This is 6 times longer than the professional grade X26 that only has 5 seconds of Neuro-Muscular Incapacitation. Since the Pulse will continue to tase your threat for 30 seconds, you can put the Pulse down and use that 30 seconds to remove yourself from the threat. You can override the Pulse by flipping the safety back on. Or after 30 seconds, you can pull the trigger and the Pulse will tase for another 30 seconds.

Toxic symbol

You can see the two probes hit its mark. But did they do anything? I am not sure since the conductive target is hidden behind the vest. The probes were stopped by the insulation of the jacket. I ended up having to cut the jacket off because the zipper got stuck. You can see how much insulation there is and it is not a surprise the probes were stopped early. I have my doubts that the probes would be effective if you shot someone in the winter, wearing a thick jacket,

The symbol was adopted as a standard in the US by ANSI in 1969.[10][12] It was first documented as an international symbol in 1963 in International Organization for Standardization (ISO) recommendation R.361.[13] In 1974, after approval by national standards bodies, the symbol became an international standard as ISO 361 Basic ionizing radiation symbol.[14] The standard specifies the shape, proportions, application and restrictions on the use of the symbol. It may be used to signify the actual or potential presence of ionizing radiation. It is not used for non-ionizing electromagnetic waves or sound waves. The standard does not specify the radiation levels at which it is to be used.[14]

The United Nations has designed GHS hazard pictograms and GHS hazard statements to internationally harmonize chemical hazard warnings under the Globally Harmonized System of Classification and Labelling of Chemicals. These symbols have gradually replaced nation and region specific systems such as the European Union's Directive 67/548/EEC symbols,[28] Canada's Workplace Hazardous Materials Information System.[29] It has also been adopted in the United States for materials being sold and shipped by manufacturers, distributors and importers.[30] The USA previously did not mandate a specific system, instead allowing any system, provided it had met certain requirements.[31]

As I was testing the new Pulse, I thought of other tests that could cause the Pulse to not work properly. Remember the two foot spread of the probes? I was curious what would happen if I attempted to shoot the Pulse sideways. Yes, just like Steve Carell in the movie Date Night, I tried a kill shot. As expected, I missed the target. As mentioned above, the top probe has a tendency to fire straight, while the other fires at an angle. Watch the video below. You will see the probe closest to the sights fires pretty much where I was aiming while the other probe flies past the target entirely. It also pulled the wire out of the cartridge.

Health hazard symbol

On roadside warning signs, an exclamation mark is often used to draw attention to a generic warning of danger, hazards, and the unexpected. In Europe and elsewhere in the world (except North America and Australia), this type of sign is used if there are no more-specific signs to denote a particular hazard.[6][7] When used for traffic signs, it is accompanied by a supplementary sign describing the hazard, usually mounted under the exclamation mark.

That map is not totally accurate, for instance several cities in WA outlaw use and possession of Taser's. Tacoma WA just removed their restrictions but they continue in Seattle for example as guns in this state are only controlled at the state level, energy weapons not so much.

According to Baldwin, who was assigned by Dow to its development: "We wanted something that was memorable but meaningless, so we could educate people as to what it means." In an article in Science in 1967, the symbol was presented as the new standard for all biological hazards ("biohazards"). The article explained that over 40 symbols were drawn up by Dow's artists, and all of the symbols investigated had to meet a number of criteria: "(i) striking in form in order to draw immediate attention; (ii) unique and unambiguous, in order not to be confused with symbols used for other purposes; (iii) quickly recognizable and easily recalled; (iv) easily stenciled; (v) symmetrical, in order to appear identical from all angles of approach; and (vi) acceptable to groups of varying ethnic backgrounds." The chosen scored the best on nationwide testing for uniqueness and memorability.[20]

The European Union aligned its regulations with the GHS standards in 2008 with the adoption of CLP Regulation, replacing its existing Directive 67/548/EEC symbols during the mid-2010s, and requiring use of GHS symbols after 1 June 2017.[32][33] Since 2015, European standards are set by:

The Pulse has molded in polymer sights. The front sight is molded bright yellow plastic which provides good contrast for aiming. However I will be honest, I never used them.

A replacement product assumes the remaining warranty of the original product or 90-days from the date of replacement, whichever provides longer coverage to the Purchaser. TASER International’s Lifetime Replacement Guarantee is not available or applicable:

The Workplace Hazardous Materials Information System, or WHMIS, is Canada's national workplace hazard communication standard, first introduced in 1988, and included eight chemical hazard symbols.[34] This system was brought into alignment with GHS in 2015, with a gradual phase in of GHS symbols and label designs through 15 December 2025.[29] The WHMIS system does deviate from GHS by retaining the former WHMIS symbol for Class 3, Division 3, biohazardous infectious materials, as GHS lacks a biological hazard symbol.[29]

The Pulse trigger is ridiculously light weight. Often the Pulse fired off a little too soon for me. Unlike your stereo typical stun gun, that only have fixed electrodes, the Pulse has both contact distance points and aerial launched probes attached to leads. The probes only have an effective range of 15 feet.

On February 15, 2007, two groups—the International Atomic Energy Agency (IAEA) and the International Organization for Standardization (ISO)—jointly announced the adoption of a new ionizing radiation warning symbol to supplement the traditional trefoil symbol. The new symbol, to be used on sealed radiation sources, is aimed at alerting anyone, anywhere to the danger of being close to a strong source of ionizing radiation.[17] It depicts, on a red background, a black trefoil with waves of radiation streaming from it, along with a black skull and crossbones, and a running figure with an arrow pointing away from the scene. The radiating trefoil suggests the presence of radiation, while the red background and the skull and crossbones warn of danger. The figure running away from the scene is meant to suggest taking action to avoid the labeled material. The new symbol is not intended to be generally visible, but rather to appear on internal components of devices that house radiation sources so that if anybody attempts to disassemble such devices they will see an explicit warning not to proceed any further.[18][19]

TASER is the name in the industry for less lethal tools. They provide electrical muscular override tools for Law Enforcement. The TASER Pulse is a “civilian legal” less lethal tool shaped like a subcompact handgun. Unfortunately, my editors told me I was not allowed to shoot the TASER Pulse at people or animals for this review. But, we don’t test firearms on people or animals when we review them so this is no different than any ordinary firearm review.

A chemical hazard symbol is a pictogram applied to containers and storage areas of dangerous chemical compounds to indicate the specific hazard, and thus the required precautions. There are several systems of labels, depending on the purpose, such as on the container for transportation, containers for end-use, or on a vehicle during transportation.

The skull-and-crossbones symbol, consisting of a human skull and two bones crossed together behind the skull, is today generally used as a warning of danger of death, particularly in regard to poisonous substances.

The darts will penetrate all but the thickest clothing and the electricity will also jump up to two inches of combined distances between the probes and the skin.

Hazard symbols are recognizable symbols designed to warn about hazardous or dangerous materials, locations, or objects, including electromagnetic fields, electric currents; harsh, toxic or unstable chemicals (acids, poisons, explosives); and radioactivity. The use of hazard symbols is often regulated by law and directed by standards organizations. Hazard symbols may appear with different colors, backgrounds, borders, and supplemental information in order to specify the type of hazard and the level of threat (for example, toxicity classes). Warning symbols are used in many places in place of or in addition to written warnings as they are quickly recognized (faster than reading a written warning) and more universally understood, as the same symbol can be recognized as having the same meaning to speakers of different languages.[citation needed]

The Taser Pulse comes packaged with two cartridges and a neoprene slip cover. The cover is like a sock. It covers the top part of the taser. To remove the cover, you just pull up on that loop at the back of the grip. Lift it up and forward off the Taser Pulse.

The LED light is not very bright but it can help to illuminate your target. It is just not bright enough to temporarily blind your target.

hazard symbols意思

What does the TASER do to live people? Well as I mentioned earlier, I was unable to shoot this at people or animals. However thanks to the internet, we have examples.

The symbol, or some variation thereof, specifically with the bones (or swords) below the skull, was also featured on the Jolly Roger, the traditional flag of European and American seagoing pirates. It is also part of the Canadian WHMIS home symbols placed on containers to warn that the contents are poisonous.

So when I got the TASER Pulse, I tried to find out what powered it. There is a small lithium battery stored in the grip. However, when taking the batteries out to take photos of it, I managed to pull the wires out of the plug.
