SECTION 2: Hazards identification

2(a) Classification of chemical in accordance with paragraph (d) of §1910.1200 Flammable 2(b) Signal word, hazard statement(s), symbol(s) and precautionary statement(s) in accordance with paragraph (f) of §1910.1200

Precautionary statements

Danger (H280) Contains Gases (General P210) Keep away from heat/sparks/open under Pressure; may flames/hot surfaces. - No smoking. explode if heated. (Reaction P377 + P381) Leaking gas fire: Do not (H220) Extremely extinguish, unless leak can be stopped safely. Eliminate flammable gas. Dissolved Gas all ignition sources if safe to do so. (P410 + P403) Protect from sunlight. Store in a well ventilated place. 2(c) Describe any hazard not otherwise classified that have been identified during the classification process • Acetylene is a lighter than air gas. It may escape past closure seals that are air-tight and accumulated in inadequately vented storage spaces. • By-products generated in use, such as welding and flame cutting, may generate hazardous fumes and gases. • Large amount of potential energy resulting from compression of the gas makes the cylinder a potential rocket or fragmentation bomb. 2(d) Where an ingredient with unknown acute toxicity is used in a mixture at a concentration = 1% and the mixture is not classified based on testing of the mixture as a whole, a statement that X% of the mixture consist of ingredient(s) of unknown acute toxicity is required. Acetylene CAS No. 74-86-2 consists of 0% of unknown acute toxicity.
