PRODUCT CATALOG - SAFETY INFORMATION
ISOCYANATE CATALYSTS
Isocyanate catalysts contain small quantities of Isocyanate and Ethylene Glycol Monoethyl Ether Acetate. In spite of the contents of these two noxious ingredients, paints containing Isocyanate Catalysts, may be used without risk to health providing the following recommendations are observed together with generally good standards of industrial hygiene.
PERSONNEL
Persons with a history of Asthma or similar respiratory conditions should not be engaged in any process which involves the use of Isocyanate.
PLANT DESIGN
Spraying operations which involve products containing the above mentioned ingredients should be carried out in suitable spray booths or enclosures under exhaust ventilation so that all spray mists are effectively removed from the spray operators breathing zone and conducted away from the spray booth area.
EXHAUST VENTILATION
Exhaust ventilation should be designed so that spray mist is conducted away to a safe place. Air flow velocities should be sufficient to disperse spray mists and vapors effectively.
Normally, an air flow velocity of one meter per second may be considered sufficient.
BREATHING APPARATUS
All operators working inside of the spray booth area (whether spraying or not), should wear compressed air line breathing apparatus conforming to BS4667: Part 3:1974 or other air fed equipment which provide equivalent protection both during the spraying process and until such time as all spray mists have cleared.
The equipment used to supply the air to the breathing apparatus should conform to BS4275_1975. Care should be taken to ensure that the supply of air to the equipment is drawn from an uncontaminated source and that an efficient oil, water and fume filter is fitted to provide breathable air.
Where operators are required to work within the booth, an alarm system should be fitted to warn the user of the apparatus in the event of air pressure failure; when the air pressure falls to the minimum safe working level of the apparatus.
Persons entering the spray booth or enclosure for short periods (less than 15 minutes) when spraying is taking place may be protected from inhaling spray mist by wearing a suitable respirator conforming to BS2091: 1961 fitted with a type "CC" Charcoal canister.
SAFETY HANDLING
Persons engaged in handling and mixing paints containing Isocyanate Catalysts, should wear protective clothing, avoiding skin and eye contact. In the event of splashes on the skin or into the eyes, wash the affected area with copious amounts of water and seek medical aid immediately.
SANDING
It is recommended that all persons engaged in dry sanding of paint finishes, known or suspected to be of a type hardened by Isocyanate, take the same precautions and wear the same breathing apparatus as recommended for operators spraying products containing Isocyanate.
STORAGE
Store in tightly sealed containers, at ambient temperatures. Protect from moisture, evaporation and foreign materials. Process ability of Isocyanates and products containing Isocyanates can be adversely affected by evaporation and contamination.
SHELF LIFE
12 months, provided materials are kept in sealed original containers under specified conditions.
