Persons working with ammonia under routine circumstances of operations or maintenance should wear chemical splash-proof googles and rubber or plastic gauntlet ploves impervious to ammonia to protect critical body areas which are most vulnerable to contact with ammonia should aminor leak occur. Each location having an installation should have readily available and freely accessible, emergency protective and safety equipment as required. They should be well identified by appropriate signs.

Depending upon the size and nature of the installation, emergency protective and safety equipment may include one or more of the following:

a- Safety shower:

Parts of the body injured by contact with ammonia must be flooded immediately with a large quantity of water.

b- Respirtory devices:

At least 2 full face GAS MASK with an ammonia must be maintained at each station. It should be noted that these canisters are limited to brief periods of use not exceeding 15 minutes and for use in concentrations of ammonia in air by volume not exceed 2%. A person wearing a mask must leave a contaminated area immediately on detecting an odor of ammonia or experienceing difficulty in breathing. These are indications that the mask or canister is not functioning properly, that the ammonia concentration is excessive, or that adequate oxygene is not available.

Any repiratory device must be used and maintained in accordance with manufacturer's instructions. A person who uses it should have received through training and practice.

c- Protective clothing:

Emergency or rescuse personnel required to work in high ammonia concentrations should wear protective gloves, boots, pants and jacket impevious to ammonia. A hard hat should be worn as required by plant practice or dictated by special hazards.

d- Rescue harness:

A safety belt and lifeline should be worn by an individual using respiratory equipment and entering contaminated air in a confined location. Another person also wearing respiratory equipment and protective clothing should be located outside the contaminated area to act in case of emergency.

e- Stretcher and Blanket:

Inadequate facilities for transporting a seriously injured person from the scene of an accident to a first aid station can add to the seriousness of the injury. A stretcher provides the most acceptable method of hand transportation and it may be used as a temporary cot at the first aid station or during transit in a vehicle.

f- Safety training:

Safety training is the responsibility of management and should be given to new and old employees at periodic intervals as neded to maintain high proficiency levels. Included should be written or oral instructions followed by drills regarding location, purpose of use of personal and protective clothing, equipment, safety showers or other water sources, first aid supplies and shut-down equipment such as valves and switches.
