Standard 29 CFR 1910.269 – for electric power generation, transmission, and distribution, contained comprehensive regulations and addressed control of hazardous energy sources for power plant locations; Standards are compared with those of IEEE and National Fire Protection Association. [4] [5]
The Consumer Product Safety Commission (CPSC) regulates consumer fireworks at the federal level through the Federal Hazardous Substances Act (FHSA). The National Fire Protection Association (NFPA) sets forth a set of codes that give the minimum standards of display fireworks use and safety in the U.S. Both state and local jurisdictions can ...
DDT remains on WHO's list of insecticides recommended for IRS. After the appointment of Arata Kochi as head of its anti-malaria division, WHO's policy shifted from recommending IRS only in areas of seasonal or episodic transmission of malaria, to advocating it in areas of continuous, intense transmission.

The explosion led to new safety standards in the milling industry. [27] A dust explosion is the rapid combustion of fine particles suspended in the air within an enclosed location. Dust explosions can occur where any dispersed powdered combustible material is present in high-enough concentrations in the atmosphere or other oxidizing gaseous ...
Lithium will ignite and burn in oxygen when exposed to water or water vapor. In moist air, lithium rapidly tarnishes to form a black coating of lithium hydroxide (LiOH and LiOH·H 2 O), lithium nitride (Li 3 N) and lithium carbonate (Li 2 CO 3 , the result of a secondary reaction between LiOH and CO 2 ).

The standard enthalpy change of combustion, ΔH° c, expressed per mole of ammonia and with condensation of the water formed, is −382.81 kJ/mol. Dinitrogen is the thermodynamic product of combustion: all nitrogen oxides are unstable with respect to N 2 and O 2, which is the principle behind the catalytic converter.
The primary purpose of CO detectors is to sound an alarm to warn occupants of an enclosed space of a dangerous level of carbon monoxide. The alarm should sound within 60 minutes if the concentration rises to 70 PPM, within 10 minutes at 150 PPM, in 4 minutes at 400 PPM, and immediately at 500 PPM or greater.
Nitrogen dioxide is a reddish-brown gas with a pungent, acrid odor above 21.2 °C (70.2 °F; 294.3 K) and becomes a yellowish-brown liquid below 21.2 °C (70.2 °F; 294.3 K). It forms an equilibrium with its dimer , dinitrogen tetroxide ( N 2 O 4 ), and converts almost entirely to N 2 O 4 below −11.2 °C (11.8 °F; 261.9 K).
