Hurricane Harvey decimated large swathes of south Texas coastline, submerging the state’s largest city in the worst floods ever recorded. The future looks just as grim; the aftermath may become a perfect storm of safety hazards for those helping to rebuild the area. A tight construction labor market, contaminated flood waters, and the dangers of demolition and construction intersect to create the potential for multiple safety and health hazards for construction workers.
From toxic waste spread by flood waters and mosquito-borne illness to structural instability, recovery workers are surrounded by nearly every safety hazard addressed by OSHA.
OSHA Fact Sheet 3698 - Keeping Workers Safe during Disaster Cleanup and Recovery
OSHA provides a fact sheet covering the various dangers and their potential hazards as well as protective measures. It includes information about:
The hazards of these areas can be mitigated or avoided with the proper use of personal protective equipment and safety training.
At issue is that demolition and construction companies will probably hire inexperienced workers. It may be the case particularly with low skill jobs such as tearing out and hauling away debris, tree trimming and cutting, and structural framing.
Where will these workers obtain personal protective equipment and the training to use it properly? Will they receive proper training in safety measures, particularly those faced in a flood zone? Or will they face these dangers without understanding the risks?
Train All Workers Responsibility for Safety
For companies hiring, the first concern should be to provide them with Personal Protective Equipment, or PPE for short, and train them on its use. Each day, a supervisor should organise training sessions for everyone to reinforce training of new workers. Each day, a supervisor should ensure the PPE is maintained and stored safely. The proper and consistent use of the appropriate PPE is second only to thorough and frequent hand washing in keeping workers free from injury and illness.
Training in electrical safety is crucial.
Always Assume Power Lines and Outlets Are Energized.
Generator safety includes understanding the potential for carbon monoxide (CO) poisoning. Generators should never be used in enclosed spaces; you need plenty of ventilation. Also, they should not be placed near open doors or windows where CO might drift into an enclosed space.
Symptoms of carbon monoxide exposure include dizziness, headaches, nausea, and tiredness. If a worker begins to feel ill, he or she should seek fresh air immediately.
Generators also become very hot while they are in use. Train workers to keep flammable substances away from the motor, especially when refueling. The generator should be shut down and allowed to cool so spilled fuel does not ignite.
Mold is sure to be an issue. Mold mitigation efforts must begin within 48 hours of a flood event. Unfortunately, Hurricane Harvey’s continued presence used up that safety margin. As workers enter structures, the risk of mold and mold spore contamination is high. Workers should bring or be provided with full or partial N, R, or P-100 respirators to prevent respiratory illness.
Any material that has been soaked in floodwater must be taken out of structures for disposal. If removal is from an upper story, use a covered chute with a door at the exit to prevent the spread of mold spores. Disinfect all PPE, surfaces, and fabric with 1/2 cup household bleach per gallon of water. Do not mix the bleach solution with any product that contains ammonia.
Many buildings were completely demolished by hurricane-force winds and debris has been scattered everywhere. However, some remained standing. Before anyone enters a building, establish its stability.
While some structures will appear to be in danger of imminent collapse, do not allow workers into any structure until it has been assessed. Seemingly complete structures may have weaknesses not visible to the untrained eye.
Now and in the months ahead, people who have never worked in demolition or construction will be doing both. The pipeline for skilled and experienced construction workers has been constricted for far too long, and we now find ourselves in a bind.
If and when companies hire new workers, regardless of their experience, they should concentrate on safety training first, before allowing anyone to enter the disaster zone to help with cleanup.
