The demands for infrastructure repairs
could not be met without specific construction requirements such as sealants. Sealants
are used in building and construction industry both for structural and
decorative purposes. It is commonly used in residential housing, construction,
car maintenance and infrastructure development. Despite its different uses, sealants
may pose risk if mishandled incorrectly. Here are some of the general guides in
dealing with sealants.
Hygiene
Food and drinks should be prohibited
inside the storage of sealants. Some adhesives emit dusts or toxic vapours so
suitable dust masks, respirators and adequate ventilation should be provided during
application. Skin contact should be minimised. Manufacturers should advise on
cleansing and barrier creams for their products. Suitable protective clothing
and eye protection may be needed if you are using a strong sealant.
Allergies,
Spillage and Waste Disposal
A possibility that an individual may
be allergic to a substance is always present. There is no easy solution to this
problem if physical protection is inadequate. Complete avoidance to the
exposure of these products may be the only remedy.
Spillages of any type should be
attended immediately. Water-based sealants may be washed away with water before
it dries. Avoid disposal into drains as this may clog it up. Another method is
to soak up spillage with a material which can be closed in a suitable container
for proper disposal. This is specifically for solvent-based sealants using
sand, clay or powdered limestone as the absorbent material.
Utmost care should be taken into
account when disposing empty solvent-based adhesives in order to avoid fire
hazard. Empty containers must be carefully punctured or left open to ensure
that no vapour is trapped under pressure, taking concern about the usual
precautions on flammable materials. In all cases, the manufacturer’s
instructions or label accompanying the product should be observed.
Storage
Some sealants should be
stored in suitable fireproof areas according to the requirements of authorities
and the manufacturer. All sealants should be stored in dry condition and
reasonable temperatures preferably 5C – 30C. To ensure that the shelf life of
adhesive products is not exceeded, strict rotation of stock should be observed
and possible safety hazards from ageing should be avoided.
Remember to read the packaging before
anything else. Keep it even after your application. Always ask an expert if you
are unsure of anything. Keeping these things in mind ensures safety and of
course, good sealant application.
