Chemical Exposure at Work — Injury Statistics and Claims Information
Chemical Exposure at Work
Chemical exposure incidents are currently decreasing
Chemical burns and corrosive injuries account for 79 percent of all reported exposure incidents. These events often result in immediate, life-altering damage to skin and internal systems.
The most severe cases frequently involve multiple body parts or critical systems. Workers often face long-term complications from exposure to corrosive acids and bases that penetrate protective gear.
What's Driving the Trend?
Over the last decade, reported severe chemical exposure incidents have decreased by 20.2 percent. Despite this decline, corrosive acids and cleaning agents remain the primary sources of injury in high-risk environments.
Manufacturing accounts for 44.6 percent of all severe cases, largely due to the volume of hazardous materials handled daily. Construction and transportation sectors also show persistent risks where chemical handling protocols frequently fail.
Injury Types from Chemical Exposure
Top causes based on OSHA incident reports
Chemical exposure occurs when hazardous substances like corrosive acids, bases, and industrial cleaning agents contact human tissue. These incidents often happen when containment systems fail, such as ruptured sight glasses or leaking chemical lines. Workers are frequently injured when chemicals spray during maintenance, spill from damaged containers, or seep through inadequate protective clothing.
| Injury Type | Incidents | |
|---|---|---|
| 1 | Chemical burns, corrosions | 632 |
| 2 | Effects of poison, toxic, or allergenic exposure— unspecified | 88 |
| 3 | Traumatic injuries or exposures— unspecified | 41 |
| 4 | Allergic and irritant dermatitis— acute | 12 |
| 5 | Infections of the skin and subcutaneous tissue | 11 |
| 6 | Anaphylactic shock, anaphylaxis | 3 |
| 7 | Cuts, lacerations, punctures without injury to internal structures | 2 |
| 8 | Bacterial diseases— unspecified | 2 |
Why This Matters for Your Case
Employers must comply with 29 CFR 1910.1200, the Hazard Communication Standard, which mandates proper labeling and safety data sheets for all hazardous chemicals. Failure to provide adequate personal protective equipment or maintain safe containment systems often constitutes a violation of the General Duty Clause of the Occupational Safety and Health Act.
Industries with Most Chemical Exposure
Where these injuries occur most frequently
Manufacturing leads with 44.6 percent of all severe exposure cases, primarily because workers interact with large-scale chemical processing equipment daily. Construction and transportation follow, where the movement of hazardous materials and the use of industrial cleaners create high-risk environments for accidental contact.
High-Risk Industries and Your Rights
In manufacturing and construction, employers are legally required to adhere to 29 CFR 1910.132 for personal protective equipment and 29 CFR 1910.141 for sanitation and hygiene. These standards dictate the necessity of chemical-resistant gear and emergency eyewash stations to mitigate injury when containment fails.
Real Incident Reports
From actual OSHA investigation files
Reported incidents reveal a recurring pattern of equipment failure and inadequate protective measures during routine maintenance. Workers are frequently exposed when pressurized systems rupture or when handling chemicals without sufficient barrier protection, leading to severe burns on the upper body, legs, and eyes.
"Employees were investigating the vapor conditions at the purification vent scrubber after a restart. Employees were looking through the sight glass, when the glass ruptured, releasing chemical vapors. Two employees sustained chemical burns to their upper body."
"An employee was delivering a package when it leaked acid on their skin, burning it."
"An employee was de-bundling cubed feedstock consisting of plastic barrels. The employee was putting feedstock into the shredders manually. She lifted a drum to put it in the shredding machine and sulfuric acid spilled down the front of her left leg. The employee sustained chemical burns to her lower leg requiring hospitalization."
"An employee was washing the tunnel equipment area using a sprayer and a chemical containing 5-10% hydrofluoric acid. The chemical seeped into his clothing and caused chemical burns to his abdomen and upper thighs. The employee was hospitalized."
"Three maintenance employees were working on chemical lines feeding into a large above ground wastewater treatment tank. Sodium hydroxide and sulfuric acid reacted in a floor drain and the chemicals sprayed onto the three employees. One employee was taken to the hospital for burns to his eyes."
"An employee was lifting a level controller that had been on a vertical tank. Residual phenol-containing liquid dripped onto his right thigh, causing a chemical burn. He was hospitalized."
"An employee was using a pump to transfer hazardous waste between barrels when the pump broke and sprayed the mixture into the employee's face, resulting in chemical burns to their face and eyes."
"An employee was cleaning a filler machine. The machine began to leak and was paused. Believing that the machine had been set to abort, the employee started to remove a clamp by the leak. Caustic wash sprayed out, striking the employee in the face and shoulder. He suffered a chemical burn to the side of the face and in the mouth."
"An employee was tightening a cooling hose clamp when it failed. Cooling chemicals sprayed onto his arms, stomach, and inner thighs, causing burns."
"An employee was changing a part in a mixing room. While removing the part, the employee came into contact with a caustic chemical that burned the employee's left hand and arm. The employee was hospitalized."
