| 3 | Spill: absorb with dry sand; neutralise acrylic acid with soda ash |
| 4 | Skin: flush 20 min; sensitised workers remove from exposure |
| 1 | Same as solid cyanide: 108 immediately |
| 2 | Do NOT attempt mouth-to-mouth — rescuer risk |
| 3 | Amyl nitrite inhalation; IV sodium thiosulphate in hospital |
| 4 | Bath neutralisation: ferrous sulphate solution raises pH and precipitates iron-cyanide complex |

| 4 | Notify DISH for spill >10 litres |
| 1 | Move to fresh air; O₂; medical if symptomatic |
| 2 | Spill: absorb with dry earth; no sewers (scheduled waste) |
| 3 | Potential phosgene formation near hot surfaces — 24 hr hospital observation |
| 4 | Biological monitoring: trichloroacetic acid in urine |

| 2 | Phosgene risk in fire — SCBA mandatory |
| 3 | Spill: contain; ventilate; no sewers (ODS + toxic scheduled waste) |
| 4 | Liver/kidney function tests at 24–72 hr post exposure |
