• For the spraying inside of occupied buildings:
.1 Delimit the working space (with a polyethylene if required).
.2 All the ventilation ducts must be sealed before the spraying.
.3 Install a fan extracting the air outside of the building
.4 The workspace, in retrofit construction (occupied buildings), must be under negative
pressure at a minimum exfiltration rate of 0.3 air changes per hour.
.5 The workspace, in retrofit construction, must be under negative pressure for a minimum of
24 hrs.
.6 Make sure that everyone in the workspace has respiratory protective equipment and a
personal protective equipment in conformity with provincial regulations and the
CAN/ULC-S705.2 standard.
.4 Protect adjacent surfaces, windows, equipment, and site areas from damage of over spray.
