- Health (blue): 1 - poses no health hazard, requires no precautions, and would offer no hazard beyond that of ordinary combustible materials.
- Flammability (red): 1 - materials that require considerable preheating, under all ambient temperature conditions, before ignition and combustion can occur. Flash point above 250 °C.
- Instability–reactivity (yellow): 0 - normally stable, even under fire exposure conditions, and is not reactive with water.
- Special notice (white): -

Protective measures
Gloves
Occupational Safety and Health Act of 1970 and OSHA Glove Selection Chart categorize gloves into four protection levels (very good, good, fair, poor (not recommended)) for given chemical. The levels of protection against anhydrous sodium acetate for four types of gloves are:
- Neoprene: very good.
- Natural latex or rubber: very good.
- Buthyl: very good.
- Nitrile: very good.
Safety goggles
- Always wear safety goggles when handling anhydrous sodium acetate. Corrective glasses are not considered safety googles.
- Handle anhydrous sodium acetate inside the fume hood only (with exception of moving the closed bottle to and from the storage cabinet).
Clothing
- Wear long trousers and fully covered shoes.
- Contact lenses are forbidden while working with chemical substances, even in combination with safety glasses.
- Do not wear cosmetics.
- Do not wear synthetic clothing while working with flammable liquids or gases or when a hazard is present as these materials tend to melt and stick to exposed skin.
- Do not wear headphones.
Spill management
- Use personal protective equipment.
- Avoid dust formation, avoid breathing dust.
- Avoid breathing vapors or mist.
- Ensure adequate ventilation.
- Evacuate personnel to safe areas.
- Sweep up without creating dust and arrange disposal.
- Do not let it enter drain.
- If a spill happened outside the fume hood (on the floor or desktop) contact Dr Jakub Tkaczuk (+41 44 632 31 62) and the ETH Emergency Desk (+41 44 342 11 88 from mobile or 888 from landline).
