Environmental Hazard Remediation After Tropical Storm Marco and Hurricane Laura

If current projections hold, Tropical Storm Marco will make landfall along the Louisiana coast, followed soon after by Hurricane Laura. Environmental hazard remediation after Tropical Storm Marco and Hurricane Laura will involve mold remediation and water damage restoration. That’s a given. But there are other environmental hazards often present in our homes and buildings – asbestos, lead, PCB, and mercury.

Typically, storm coverage emphasizes mold remediation. I get it – mold remediation has been a hot topic for years now, and will continue to be, especially every time we have a tropical storm or hurricane. But everyone involved with environmental hazard remediation and recovery has to consider the other environmental cleanup hazards they could encounter.

Environmental hazard remediation after tropical storms takes time. Response work, particularly environmental cleanup, must balance speediness and caution. This is particularly important this week since we’ll want to get out and assess damage as soon as Tropical Storm Marco clears out. But here’s the problem: Hurricane Laura is going to make landfall right about the time that’s happening. Not the best time to get out and take a look at what recovery is needed since Hurricane Laura may cause more damage.

I know everyone wants to get in and get everything cleaned up and put back together. But sometimes hasty cleanup efforts can make more of a mess if we don’t slow down and assess all the potential environmental hazards in the work area.

My advice may not make much sense, and I know from my own experience that you want to get things fixed and back to normal as soon as possible. Things may feel (or literally are) upside down after tropical storms. Especially this week when we are going to take a hit from two storms almost literally back to back.

Remember though, your safety is the most important consideration. Whether it’s water in the roadways, downed power lines, unstable structures, or contaminated water, make sure it’s safe to move around before you try to get in and assess the damage and environmental hazards.

And when the storm is over, we often see hot temperatures return. Dehydration, heat exhaustion, and heat stroke are common problems.

Take care of yourself, then worry about contents – it’s worth repeating that you can always replace buildings and contents, but not people.

I won’t get too far into avoiding mold and mold remediation, other than to link to our other blog posts on avoiding mold. The important thing to remember is to determine the cause of the water or moisture problem that caused the mold.

Maybe the tropical storm or hurricane was the only cause of the mold. Or maybe there’s an ongoing moisture problem that existed before the storm. Find the cause, get the building dried out, cleaned up, and keep the mold from coming back.

One other quick reminder on water damage restoration and mold remediation: there is no such thing as a Mold Free Certificate. There’s no requirement to get your home or building certified as “mold free” to make sure you can sell or rent a home or building. Anyone trying to sell you a mold free certificate is trying to scam you. Period. Don’t waste your money.

Back to environmental hazard remediation. Tropical Storm Marco and Hurricane Laura are probably going to bring about a lot of renovation and demolition work that will disturb asbestos and lead. Don’t get so focused on mold that you ignore other hazards.

 


Remediation and Demolition Work Areas May Contain Asbestos, Lead, PCB, and Mercury

 

Asbestos and lead are more commonplace than you may think. It’s easy to encounter asbestos and lead when gutting out buildings – walls and floors often contain asbestos and lead. 

And don’t listen to anyone that tells you there’s a date cutoff for use of asbestos or lead.

Many contractors think to check for asbestos and lead before beginning demolition. Others, however, don’t. Contractors may put (or try to anyway) the burden on you or the building owner to notify them of hazardous materials and conditions.

Giving the contractor a comprehensive scope of work is a great idea. While developing the scope takes time, everyone should have a clear understanding of what’s expected from everyone on the project team. And with everything going on, many times emotion clouds people’s recollection of conversations.

Keep in mind the so-called “other” safety hazards. Protect your hands, eyes, head, and even your ears. Slips, trips, and falls remain the number one cause of job site injuries and deaths. Approach all environmental hazard remediation as you would a real project. After all, that’s what it is, even if you’re doing the work yourself.

Also don’t forget to protect yourself against hazards that may be present in the cleaning chemicals you (or your contractors) will use.

It’s worth mentioning one more time that structures and walking surfaces may be unstable or unsafe. If there’s any doubt, don’t go in. Get out at the first sign of trouble.

You’ve heard this phrase when talking about driving into deep water: “turn around, don’t drown”. Well, here’s one for when you’re thinking about going into a building after a storm: “when in doubt, stay out”.

If you’re like me and not in the path of Hurricane Laura, you’ve spent a good bit of time watching Hurricane Laura news coverage. So far it looks like the surge wasn’t nearly as bad as predicted, but Hurricane Laura caused a tremendous amount of damage to Cameron and Calcasieu parishes and the surrounding areas. It’s also too soon to tell how much damage Hurricane Laura will cause as the storm moves inland and dissipates. What’s certain though, is Hurricane Laura will leave a considerable amount of water damage, resulting in water damage restoration and mold remediation. Hurricane Laura environmental cleanup is going to be a huge undertaking and will cause disturbance of asbestos, lead, PCB, and mercury. Proper removal and disposal of those materials is super important. Typically, storm coverage emphasizes water damage and mold remediation. Water damage restoration and mold remediation after Hurricane Laura will be the most obvious cleanup and restoration tasks.
