Hazardous Materials Enclosure or Containments

August 8th, 2017 | in Abatement Services

At Enviro-Vac, we pride ourselves in providing safe, OSHA approved and professionally constructed high-risk containments for hazardous materials abatement and doing so with the attention to detail for which our clients in Canada have become accustomed.

Airtight, negative pressure enclosures or containments that are smoke tested to confirm effectiveness are required during high-risk, hazardous materials abatement. Such enclosures are pressure tested and monitored to verify the negative pressure variance between the interior of the enclosure and the surrounding space. There are many factors to consider when designing a negative pressure enclosure, factors that include; penetrations through ceilings, ducting etc., negative pressure volume/flow rates, airlock & decontamination room configurations, access/egress door openings. The shape and configuration of enclosure also impact the effectiveness of the enclosure.

The type of containment installed for asbestos and/or other hazardous materials abatement is dependent on many additional factors and constraints including the type of abatement or decontamination work being performed. It could be a straight-forward exclusion zone or engineered shrink-wrap containment or even a complex series of inter connected negative pressure containments.

Enviro-Vac, during the past 40-years has gained extensive experience designing and erecting many different types of enclosures. This experience has provided Enviro-Vac employees with valuable insight in erecting and installing a verity of OSHA approved high-risk containments for hazardous materials abatement.
