considerable amount of paint is to be applied, a 2 ½ or 5 gallon pressure tank is usually employed.


The air compressor shall be equipped with an ASME rated air tank, a visible pressure gauge on the tank, a pressure reducer with its own gauge, a guard fully enclosing the drive belt and pulleys, and a pressure limiting switch to shut down the compressor when the system’s working pressure has been reached. The equipment should be securely mounted on a wheeled carriage for portability. For interior painting only electric motor-driven equipment shall be used.

Overpressure Protection:

When separate paint pressure tanks are used, they shall be equipped with a gauge and a relief valve to prevent overpressure. Hoses shall be rated for the maximum working pressure of the system.


A preventive maintenance program shall be implemented to cover periodic inspection and testing of all components.

Storage of compressors, hoses, paint pressure tanks and spray guns shall be in areas designated and approved by the supervisor in conjunction with the Office of Health and Safety.

Aerosol Spray Paint Cans:

The same general safety and health precautions apply to spray painting from pressurized cans as to spray painting by other means. The following specific items are noted:


Pressurized cans of spray paint are to be considered flammable materials and stored in appropriate locations.

Office desks are not to be used for the storage of pressurized cans of spray paint.

Office store rooms are not to be used for the storage of pressurized cans of spray paint unless the storage area has been designated safe for the storage of flammable materials by the Office of Health and Safety.
