If engineering controls and work practices are not effective in controlling exposure to this material, then wear suitable personal protection equipment including approved respiratory protection. Have appropriate equipment available for use in emergencies such as spills or fire.

If respiratory protection is required, institute a complete respiratory protection program including selection, fit testing, training, maintenance and inspection. Refer to the CSA Standard Z94.4-02, "Selection, Use and Care of Respirators," available from the Canadian Standards Association.

RESPIRATORY PROTECTION GUIDELINES:

No specific guidelines are available. Contact the chemical manufacturer/supplier or appropriate government agencies for advice.

Chemical safety goggles and a face shield may be necessary to prevent contact with refrigerated liquefied gas or compressed gas escaping from its cylinder.

Insulated chemical protective gloves, coveralls, boots, and/or other chemical protective clothing are required to prevent contact with refrigerated liquefied gas or compressed gas escaping from its cylinder (e.g. loose-fitting gloves, cuffless pants that are not tucked into shoes or boots, apron). Wear appropriate foot protection when handling cylinders.

Have a safety shower and eye-wash fountain readily available in the immediate work area.

For cryogenic liquid, the principle requirement is resistance to extremely low temperatures.

Guidelines for methane:

RECOMMENDED (resistance to breakthrough longer than 8 hours): Responder(TM).

Resistance of specific materials can vary from product to product. Breakthrough times are obtained under conditions of continuous contact, generally at room temperature. Evaluate resistance under conditions of use and maintain clothing carefully.

Do not smoke in work areas.

Remove clothing contaminated with liquefied gas immediately. Allow liquefied gas to evaporate from the material in a well-ventilated area or outdoors, away from all ignition sources. Launder before rewearing.
