4. FIRST AID MEASURES

Inhalation: Remove to fresh air. In case of shortness of breath, give oxygen. Immediate medical 

attention is required. 

Skin contact: Take off all contaminated clothing immediately. Wash off immediately with soap and 

plenty of water. If skin irritation persists, call a physician. Wash contaminated clothing before re-use.

Exposure controls

Engineering measures: Use local exhaust ventilation with a minimum capture velocity of 100 ft/min. 

(0.5 m/sec.) at the point of vapor evolution. Refer to the current edition of Industrial Ventilation: A 

Manual of Recommended Practice published by the American Conference of Governmental Industrial 

Hygienists for information on the design, installation, use, and maintenance of exhaust systems. 

Hygiene measures: Keep container closed when not in use. Shower or bathe at the end of working. 

Protective measures: Facilities storing or utilizing this material should be equipped with an eyewash 

facility and a safety shower. 

Individual protection measures

Eye/face protection: Tightly fitting safety goggles Eye protection worn must be compatible 

with respiratory protection system employed. 

Skin protection

Hand protection: Chemical-resistant gloves should be worn whenever this material is 

handled. The glove(s) listed below may provide protection against permeation. 

(Gloves of other chemically resistant materials may not provide adequate protection): 

4H Glove (Trademark of Safety 4 A/S of Denmark) butyl-rubber Gloves should be 

removed and replaced immediately if there is any indication of degradation or 

chemical breakthrough. Before removing gloves clean them with soap and water. 

NOTE: Material is a possible skin sensitizer. 

Other protection: Avoid all skin contact. Selection of specific personal protective 

equipment such as long sleeves, safety glasses with side shields, face shield, safety 

shoes, boots, apron, or full body suit will depend on the task. 

Respiratory protection: A respiratory protection program meeting OSHA 1910.134 and ANSI 

Z88.2 requirements or equivalent must be followed whenever workplace conditions warrant a 

respirator‟s use. None required if airborne concentrations are maintained below the exposure 

limit listed in Exposure Limit Information. Above the exposure limit: Wear a properly fitted 

NIOSH approved (or equivalent) self-contained breathing apparatus in the pressure demand 

mode, OR full-facepiece, airline respirator in the pressure demand mode with emergency 

escape provision.
