n.o.s. = not otherwise specified meaning a collective entry to which substances, mixtures, solutions or articles may be assigned if a) they are not mentioned by name in 3.2 Dangerous Goods List AND b) they exhibit chemical, physical and/or dangerous properties corresponding to the Class, classification code, packing group and the name and description of the n.o.s. entry [4]
Plastics moulding compound in dough, sheet or extruded rope form evolving flammable vapour UN 3315: 6.1: Chemical sample, toxic UN 3316: 9: Chemical kit or First Aid kit containing dangerous goods UN 3317: 4.1: 2-Amino-4,6-dinitrophenol, wetted, with not less than 20% water by mass UN 3318: 2.3
There are many codes and standards regarding hydrogen safety in storage, transport, and use. These range from federal regulations, [3] ANSI/AIAA, [4] NFPA, [5] and ISO [6] standards. The Canadian Hydrogen Safety Program concluded that hydrogen fueling is as safe as, or safer than, compressed natural gas (CNG) fueling, [7]
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
The hydroxyl radical has a very short in vivo half-life of approximately 10 −9 seconds and a high reactivity. [5] This makes it a very dangerous compound to the organism. [6] [7] Unlike superoxide, which can be detoxified by superoxide dismutase, the hydroxyl radical cannot be eliminated by an enzymatic reaction.
Explosive Dangerous Goods have compatibility group letters assigned to facilitate segregation during transport. The letters used range from A to S excluding the letters I, M, O, P, Q and R. The example above shows an explosive with a compatibility group "A" (shown as 1.1A).
Dusts also have upper and lower explosion limits, though the upper limits are hard to measure and of little practical importance. Lower flammability limits for many organic materials are in the range of 10–50 g/m 3, which is much higher than the limits set for health reasons, as is the case for the LEL of many gases and vapours. Dust clouds ...
A: hydroxyl radical (HO •); B: hydroxide ion (HO −); C: singlet oxygen (1 O 2); D: superoxide anion (O 2 •−); E: peroxide ion (O 2− 2); F: hydrogen peroxide (H 2 O 2); G: nitric oxide (NO •) In chemistry and biology, reactive oxygen species (ROS) are highly reactive chemicals formed from diatomic oxygen (O 2), water, and hydrogen ...
