Storage, handling, process hazards, PPE and emergency spill/leak procedures for 9 mineral and strong acids commonly used across Gujarat's electroplating, fertilizer, textile, dye and metal-finishing industries.
| 1 | Evacuate and isolate 50m radius |
| 2 | SCBA for responders — H₂SO₄ mist corrosive to airways |
| 3 | Contain spill with dry sand — do NOT use water on concentrated acid |
| 4 | Neutralise slowly with soda ash after dilution |
| 5 | Flush affected skin min. 20 min with water |
| 6 | Notify DISH/fire brigade if >50 litres |
| 1 | Isolate area — HCl vapour is immediately irritating |
| 2 | SCBA for responders; no bare-skin exposure |
| 3 | Neutralise spill with sodium bicarbonate; absorb with dry sand |
| 4 | Copious water flush for skin/eye contact — 20 min min. |
| 5 | Move to fresh air if inhaled; seek medical attention |
| 1 | SCBA mandatory — NOₓ causes delayed lung damage 4–24 hr later |
| 2 | Keep victim under medical observation even if asymptomatic |
| 3 | Dry earth/vermiculite for containment — no sawdust (fire risk with oxidiser) |
| 4 | Dilute slowly with water; neutralise with soda ash |
| 5 | Alert DISH if >20 litres |
| 1 | HF is a medical emergency — call 108 immediately |
| 2 | Apply calcium gluconate gel to affected area within seconds; rub continuously |
| 3 | Do NOT wait for pain — treat immediately if contact suspected |
| 4 | ECG monitoring — cardiac arrest risk from systemic fluoride |
| 5 | Isolate spill; SCBA for responders; neutralise with lime slurry |
| 1 | Full SCBA + encapsulating suit — SO₃ life-threatening at 2 ppm |
| 2 | Evacuate 100m minimum downwind |
| 3 | Apply dry lime from a distance — do NOT apply water |
| 4 | Seal container leak if safely possible; absorb with dry sand |
| 5 | Notify DISH and fire services immediately |
| 1 | Dilute spill with large volumes of water |
| 2 | Neutralise with lime or soda ash |
| 3 | Flush skin/eyes 20 min with water |
| 4 | If phosphine suspected (fish smell): evacuate; SCBA for responders |
| 1 | Small fire: CO₂ extinguisher; large: alcohol-resistant foam |
| 2 | Contain spill with dry sand; neutralise with soda ash |
| 3 | Flush skin 15 min; eye contact — 20 min flush + medical review |
| 4 | Ventilate area — vapour irritates all mucous membranes |
| 1 | Flush skin/eyes with water 20 min |
| 2 | If vapour inhaled: fresh air; bronchodilator if available; hospital |
| 3 | Spill: absorb with dry sand; neutralise with soda ash |
| 4 | CO generation risk if heating — ventilate and monitor |
| 1 | Skin: flush 20 min; chrome ulcer — hospital |
| 2 | Spill: sodium bisulphite + dilute H₂SO₄ reduces Cr(VI)→Cr(III); then lime neutralise |
| 3 | SPCB hazardous waste disposal — chrome sludge is scheduled waste |
| 4 | Report skin ulcers to DISH — occupational disease notification |
