Mold Remediation, Decontamination Chambers, and Negative Space

Mold is a serious deal — an expanding virus that can infest your entire home if you’re not careful. The scariest part is that because mold will often grow almost entirely beneath the surfaces of your home, you may not even notice the toxic fumes being produced or the deterioration of the insides of your house. Here are the steps we take to make sure hostile mold situations don’t get worse during the remediation process.

Setting up a decontamination chamber

The first thing we do when we face a mold crisis is set up a decontamination chamber. Setting up a safe place to clean off our bags and tools gives us a zone where we won’t have to worry about contaminating clean parts of the room. This is usually accomplished with a plastic sheeting that acts as an airlock around the quarantined areas. The decontamination chamber is especially important once the remediation process actually begins. Once we have our air scrubbers and air movers set up, the last thing we want to do is spread the airborne virus from room to room. According to OSHA website, “the remediation of extensive contamination (greater than 100 contiguous square feet in one area), the plan should address: work area isolation, the use of exhaust fans with HEPA filtration, and the design of airlocks/decontamination room.”

Air scrubbers and creating negative space

There are many steps to the mold remediation process, from identifying the scope of the remediation to sealing off the necessary areas and removing the mold from the premises. Here at OHI we often use machines called air scrubbers throughout the process, which are used to create negative space. The idea behind creating “negative space” is to ensure that the environment has more air being sucked in than it has air flowing in. Creating this space of negative air pressure helps to contain all the airborne particles and mold spores to ensure they don’t escape the work area. We proudly use air scrubbers and movers from Phoenix, whose products follow OSHA regulations and safety guidelines.

As mentioned above, many of the rules and procedures that go along with a mold remediation are determined by the level of contamination we are dealing with. These different levels of worker safety are often described in levels between I and IV. Not all levels require professional contractors to take care of the job — so when you spot mold, check to see how bad the situation has gotten.

Level I: Small Isolated Areas (10 sq ft or less).
– For example, ceiling tiles, small areas on walls.

Level II: Mid-sized Isolated Areas (10-30 sq ft)
– For example, individual wallboard panels.

Level III: Large Isolated Areas (30-100 sq ft)
– For example, several wallboard panels.

Level IV: Extensive Contamination (greater than 100 adjacent sq. ft in an area)

If your situation is as extensive as a Level III or Level IV, you have a serious contamination on your hands that requires a professional mold remediation job to ensure both that the workers are safe and that the mold is effectively removed. If you call OHI today, you’ll get a company whose longtime experience in the industry make us the number one choice for a serious mold remediation situation.
