| | What You Need to Know | | :--- | :--- | | 1. The Main Hazard | Not fire. It’s Chronic Health (Organ damage) and Skin Sensitization (allergy). | | 2. PPE Required | Nitrile gloves (not latex), chemical splash goggles, long sleeves. If misting, use an N95 or respirator. | | 3. First Aid (Skin) | Wash with soap & water for 15 minutes. Remove contaminated clothes. Do not use solvents (thinner, diesel) to wash skin—it drives chemicals into pores. | | 4. First Aid (Eyes) | Rinse for 15-20 minutes minimum. Call a doctor. | | 5. Spill Cleanup | Absorb with sand or vermiculite. Do not wash down drains (heavy metals/MoS₂ is an aquatic toxin - Section 12). | | 6. Storage | Keep away from strong oxidizers (bleach, peroxides). Store in sealed containers. | The Golden Rule of the Story Never trust an old MSDS. Manufacturers update SDSs when new health studies emerge (like how NALCO 8539’s liver toxicity was better understood in 2018). Always pull the current SDS from the supplier’s website or your digital SDS library before handling a chemical for the first time each shift.
