20 minutes as per prescribed procedure and proper disposal of waste as per workshop
SOP
Proper storage/disposal of sealant/adhesive
Sealant/adhesive must be stored in refrigerated storage or cool
area. Big companies installed equipment to recapture and recycle, or
properly incinerate, solvent and are less likely to change to solvent less
products.
STORAGE
The storage of adhesives and sealants should be restricted to 'NO
SMOKING' areas since even for non-flammable adhesives there is a risk that
vapors can be given off which will be converted by pyrolysis to toxic products
by a burning cigarette. All flammable adhesives should be stored in suitable
flameproof areas according to the requirements of the appropriate authorities.
All adhesives and sealants should be stored in dry conditions and reasonable
temperatures, eg. preferably between 50C-300C. Warm drums of solvent-
based adhesives should be opened slowly and carefully to allow gradual
release of internal pressure. To ensure that the useful shelf life of adhesive
products is not exceeded, strict rotation of stock should be observed and
possible safety hazards from aging avoided. In all cases, the manufacturer's
instructions and directions printed on the label should be observed.
SPILLAGE & WASTE DISPOSAL
Spillages of any type should be attended to immediately. Water-based
products can be washed away with water before they dry, provided it is
permissible to discharge this type of effluent into the drains. An alternative
method is to soak up the Spillage with an inert material, which can be placed
in a suitably closed container for disposal. This technique is particularly
appropriate for solvent based adhesives using either sand, clay or powdered
limestone as the absorbent material. Care should be taken in the disposal of full
or empty containers for solvent-based adhesives in order to avoid a latent
explosion and/or fire hazard. The empty containers should be either carefully
punctured or left open to ensure that no solvent vapor is trapped under
pressure, taking the usual precautions concerning flammable materials.
Note: Aerosol packages are pressurized and must not be punctured unless all
internal pressure has been relieved.
