Emergency Protocol for Labs, Workshops and Associated Stores

Note – This is general advice, the safety data sheet must be consulted for specific information.

Users of substances hazardous to health should know what they would do in the event of a foreseeable emergency event.

In the event of spillage outside a fume cupboard or local exhaust enclosure:
* If the substance is flammable, eliminate sources of ignition;
* Instruct others to keep at a safe distance;
* Open windows where appropriate;
* For spillage of volatile materials, evacuate the room and shut the door unless the substance has been determined to be safe to use in the open. Unless the spillage is one which may be left to clear by evaporation and ventilation, call the Fire Brigade.
* For spillage of material which has been determined safe to use in the open, absorb it onto sand or proprietary absorbent, and transfer it into a container which is put into a well-ventilated space for ultimate disposal.

Toxic Gas Leakage
If a compressed gas is leaking and cannot be shut off, feed the gas if possible into a fume cupboard or other ventilation discharging directly to the outside. If this is not possible then for a small leak, where practicable, transport the leaking gas cylinder to the open air and clear the surrounding area. Otherwise evacuate the room, if possible opening windows before leaving.

First Aid
Workers should know what help to give before qualified help arrives on the scene. There will be specific special procedures for certain activities - notably for hydrofluoric acid and cyanides, otherwise the basic procedure is as follows:
Flood thoroughly with water for at least 10 minutes. Use sterile eyewash or tap water from a clean container or run gently from a hose. Gently, but if necessary firmly, prise eyelids open. SEEK IMMEDIATE MEDICAL ATTENTION.
Drench with plenty of water. Remove contaminated clothing. Continue with running water for 10 minutes. Do not scrub or break the skin surface. Unless contact has been slight SEEK IMMEDIATE MEDICAL ATTENTION.
Remove affected personnel from area of exposure, without putting yourself in danger (i.e. do not enter a room where the general atmosphere appears to be dangerous - call the Fire Brigade). Rest them and keep them warm. Unless exposure has been slight and the patient feels quite well, SEEK IMMEDIATE MEDICAL ATTENTION.
DO NOT INDUCE VOMITING OR GIVE ANYTHING TO DRINK. If the chemical has been confined to the mouth give large amounts of water as mouth wash - ensure mouth wash is not swallowed. SEEK IMMEDIATE MEDICAL ATTENTION.

Procedure for Exposure to Arsenic

Procedure for Exposure to Organophosphates

Report accidents and incidents online via Health and Safety website. Wherever there is reason to believe that someone has had a higher than acceptable level of exposure to a substance, or where they suspect that their health might have been affected by exposure to substances at work it should be reported to the Health and Safety Adviser.

Waste Disposal

Ultimate disposal of waste should be part of the planning for any procedure.
Waste solvent should be disposed of into the containers provided for halogenated or non-halogenated waste. If it is contaminated with strong acid or alkali it should be neutralised before disposal to prevent corrosion of, and subsequent leaking from, the metal drums into which waste solvent is eventually bulked.
Other waste chemicals should be clearly identified with hazard pictograms on the container as appropriate. In some cases it will be necessary to treat the waste to make it less hazardous before the waste is accepted.
