The International Electrotechnical Commission publishes the 60079 series of standards which defines a system for classification of locations, as well as categorizing and testing of equipment designed for use in hazardous locations, known as "Ex equipment". IEC 60079-10-1 covers classification of explosive gas atmospheres, and IEC 60079-10-2 ...
HAZMAT Class 3 Flammable liquids. A flammable liquid is a liquid with flash point of not more than 60.5 °C (141 °F), or any material in a liquid phase with a flash point at or above 37.8 °C (100 °F) that is intentionally heated and offered for transportation or transported at or above its flash point in a bulk packaging.
Divisions. Division 4.1: Flammable Solid . Flammable solids are any of the following four types of materials: Desensitized Explosives: explosives that, when dry, are Explosives of Class 1 other than those of compatibility group A, which are wetted with sufficient water, alcohol, or plasticizer to suppress explosive properties; and are specifically authorized by name either in the 49CFR 172.101 ...
Intrinsic safety ( IS) is a protection technique for safe operation of electrical equipment in hazardous areas by limiting the energy, electrical and thermal, available for ignition. In signal and control circuits that can operate with low currents and voltages, the intrinsic safety approach simplifies circuits and reduces installation cost ...
Heat detector. A residential heat detector. A heat detector is a fire alarm device designed to respond when the convected thermal energy of a fire increases the temperature of a heat sensitive element. The thermal mass and conductivity of the element regulate the rate flow of heat into the element. All heat detectors have this thermal lag.
NFPA 704 safety squares on containers of ethyl alcohol and acetone. " NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response " is a standard maintained by the U.S. -based National Fire Protection Association. First "tentatively adopted as a guide" in 1960, [1] and revised several times since then, it ...
Dry firing firearms is the practice of discharging (or simulating the discharge of) a firearm without any live ammunition, or practicing with an inert laser/infrared training platform such as an iMarksman or SIRT (Shot Indicating Resetting Trigger) training pistol, and may also include the use of a target/feedback system, such as the iDryfire or LASR software.
The IP code or ingress protection code indicates how well a device is protected against water and dust. It is defined by the International Electrotechnical Commission (IEC) under the international standard IEC 60529 [1] which classifies and provides a guideline to the degree of protection provided by mechanical casings and electrical enclosures ...
