Section 2
SECTION 2: Hazards identification
Odor must not be used as a warning since the gas may deaden the sense of smell. Gas detection must be used. Odor Threshold Data 0.13 ppm – minimal perceptible odor 0.77 ppm – faint but perceptible odor 4.6 ppm – easily detectable moderate odor 27 ppm – strong unpleasant odor, but not intolerable IDHL (Immediately Dangerous to Life or Health) - 100 ppm - loss of sense of smell Classification of the substance or mixture Flammable Gas, category 1;H220 Extremely flammable gas Gas under pressure;H280 Contains gas under pressure; may explode if heated Acute toxicity(inhalation), category Fatal if inhaled 2:H330 Skin corrosion/irritation category Causes skin irritation 2;H315 Serious eye damage / eye irritation, Causes serious eye irritation category 2A;H319 Aquatic toxicity (acute), category Very toxic to aquatic life 1;H400
2.2 Label elements
Danger H220 Extremely flammable gas. H280 Contains gas under pressure; may explode if heated. H315 Causes skin irritation. H319 Causes serious eye irritation. H330 Fatal if inhaled. H400 Very toxic to aquatic life.
Prevention
[[Prevention]:]] P210 Keep away from heat, sparks, open flames, and other ignition sources - No smoking. P260 Do not breathe dust, fume, mist, vapors or spray. P264 Wash thoroughly after handling. P271 Use only outdoors or in a well-ventilated area. P273 Avoid release to the environment. P280 Wear protective gloves, eye protection, and face protection. P284 In case of inadequate ventilation, wear respiratory protection.
Response

2.3 Other hazards
CONTAINS HYDROGEN SULFIDE. Product may contain significant quantities of dissolved hydrogen sulfide gas. H2S has a broad range of effects dependent on the airborne concentration and length of exposure: 0.02 ppm odor threshold, smell of rotten eggs; 10 ppm eye and respiratory tract irritation; 100 ppm coughing, headache, dizziness, nausea, eye irritation, loss of sense of smell in minutes; 200 ppm potential for pulmonary edema after >20-30 minutes; 500 ppm loss of consciousness after short exposures, potential for respiratory arrest; >1000 ppm immediate loss of consciousness, may lead rapidly to death, prompt cardiopulmonary resuscitation may be required. Do not depend on sense of smell for warning. H2S causes rapid olfactory fatigue (deadens sense of smell). There is no evidence that H2S will accumulate in the body tissue after repeated exposure. This product contains no PBT/vPvB/vPvM chemicals. This product contains no endocrine disrupting chemicals. Does NOT contain component(s) that meet a 'definition' of per & poly fluoroalkyl substance (PFAS) per the US EPA PFASMASTER combined list of PFAS chemicals.
