You know this better than anyone else — construction is, by far, one of the most hazardous industries in the world.
From explosions and fires to toxic substances and water damage, construction sites pose many risks and dangers for construction workers and the surrounding communities.
Your construction workers are exposed to various work environment risks every day. How can you control these risks and protect your workers, assets, and reputation?
In this blog post, we will explore some of the common environmental risks in construction and offer some practical tips on how to prevent, mitigate, and manage them effectively.
1. Explosions and Fires
One tiny spark plus an exposed gas line could equal disaster.
Explosions and fires can turn any construction site into a blazing inferno, especially when dealing with flammable materials, electrical equipment, gas pipes, or welding operations.
Accidentally striking an undiscovered gas line during excavation invites catastrophe — the natural gas inside these pipes is highly flammable and potentially explosive under the right conditions.
To avoid explosions, your top priority must be to a cleanly run site:
- Provide clear trash areas for construction waste such as packaging and pallets, as well as garbage generated by workers such as food wrappers.
- Designate smoking areas away from excavations and standard trash areas.
- Never burn trash or other refuse on job sites.
Finally, your excavators should understand what utilities are known to be underground in the excavation area but still operate as if a hazardous utility could be uncovered at any time.
This means excavating deliberately without cutting more than is necessary to complete the job, and stopping excavation if a utility is uncovered.
Last but not least, heat-emitting work such as welding should be avoided near garbage or gas lines where possible.
2. Chemical Vapors
There is no shortage of potentially harmful liquids and vapors on excavation sites.
A variety of toxins may be present in the soil when excavating near biologically and chemically dangerous sites such as landfills, underground chemical storage tanks, refineries, and treatment plants.
Construction equipment and generators may also emit fumes that can be harmful if inhaled.
How do you clear the air of these often invisible threats?
Take these safety precautions to control the risk of toxicity, contamination, and other related injuries:
- If an unidentified chemical is unearthed, stop work immediately. Notify authorities to isolate the site and allow appropriate cleanup and decontamination measures.
- For known chemicals used on-site, follow all safety instructions according to the Safety Data Sheet for the chemicals.
- Avoid congregating near vehicle exhausts to reduce the inhalation of harmful fumes.
3. Dust and Suspended Particles
Dust and suspended particles plague construction job sites, obscuring vision and damaging your lungs. Silica dust in particular can cause chronic illness when inhaled regularly.
While the hazards caused by dust and suspended particles can be controlled and mitigated, it is difficult to eliminate the risk because both the weather and people not working on the job site can have an impact on the amount of dust in the air.
How can your project leaders keep the air clean?
- Firstly, superintendents should strive to minimize the amount of traffic on dry, disturbed soil to minimize soil suspension.
- A site speed limit can also be implemented to ensure workers do not unintentionally produce a potentially harmful dust cloud.
- Finally, running a water truck is a powerful tool to reduce dust by keeping soil particles grounded with water.
- Where dusty conditions can not be avoided, you should issue PPE to workers such as respirators, masks, and goggles, particularly to workers who don’t have the luxury of a cabbed vehicle.
Additionally, drastically reducing speeds or calling off work completely may be appropriate depending on the severity of the dust clouds. Health first, always.
4. Water
Even water can be a dangerous hazard on excavation sites if not properly controlled.
Water pooled on sites jeopardizes workers through drowning, shock hazards, hypothermia, and slip/fall injuries.
Falls are exacerbated by standing water and the mud left behind. Plus, electrical shock risks increase if electrical work is required on wet excavation sites.
How can your construction managers handle this risk?
Earthwork contractors can mitigate the risk of most water hazards by ensuring positive drainage throughout the site even before final grading.
This will mitigate the risk of stormwater runoff ponding on-site and generating many of the risks noted above. Cold environments may still introduce risks like hypothermia and frostbite, but removing water from the site significantly reduces these risks.
Additionally, for pit excavations, contractors should utilize pumps to de-water the pit and further mitigate the risk of drowning and other waterborne injuries.
Put safety first
Construction produces a host of risks— explosions and fires, chemical inhalation and contamination, dust inhalation, reduced visibility, and water hazards are among the serious risks, your site supervisors must control.
