COLD®22 contains odorant ethyl merchantman unless otherwise authorized. (recommended 25 mg/kg)

This is detectable to 20 % of its lower flammability limit.

Inhaled:

May Cause irritation of the respiratory tract. May also cause headaches or dizziness
At moderate exposures, Asphyxiant. Causes unconsciousness and respiratory arrest
At elevated exposures.

Eye:

Irritating if the liquid gets into the eyes, with a possible hazard from freezing due to rapid evaporation. Vapours in high concentration may also be Irritating.

Skin:

Excessive prolonged contact to the liquid to the liquid can cause skin Irritation and frostbite due to rapid evaporation.

Swallowed:

Unlikely to be a problem, owing to high evaporation rate.

Chronic:

No effected from long term industrial exposure to this product.

FIRST AID

Inhaled:

Avoid breathing vapours and fumes as much as possible. If someone is overcome by fumes, remove them to fresh air immediately. However, rescuers should avoid becoming a casualty by wearing suitable respiratory protection. If the affected individual is not breathing, administer artificial respiration.

Skin:

Avoid skin contact with the liquid. Remove contaminated clothing and wash the exposed areas with plenty of soap and water. Seek medicsl advice if irritation or frostbite (see below) occurs.

Swallowed:

Unlikely to be a problem, owing to high evaporation rate.

Frostbite:

Obtain medical assistance.
If medical advice is not available immediately, place casualty in a warm area as soon as
Possible and allow the injured area to warm gradually (further damage may occur if the area of injury warms too rapidly.) DO NOT EXPSE THE INJURED AREA TO EXCESS HEAT OR COLD (such as heat lamps, hot water, snow or ice). Gently cover or drape the injured area with clean material, such as a dressing or sheet. To relieve pain, immerse the injured area in water which is near or at body temperature (35-40 deg C). If possible, get the casualty to exercise the injured area gradually. Give them something warm to drink, BUT NO ALCOHAL. Seek medical advice as soon as possible.
