1. Understanding Oil Spill Cleanup Operations
Oil spills are releases of liquid petroleum hydrocarbons into the environment, often due to human activity. The April 2010 Gulf of Mexico oil spill, for instance, involved crude oil released from an offshore drilling rig explosion. Cleanup efforts typically focus on containing and removing oil from water and shorelines.
The National Contingency Plan serves as the federal government’s blueprint for responding to oil spills and hazardous substance releases. It promotes coordination among responders and contingency plans. A Unified Command structure, involving Federal, State, and Responsible Party representatives, oversees response efforts.
Cleanup workers may encounter various forms of crude oil:
– Fresh crude oil contains light, medium, and heavy hydrocarbons
– Weathered crude or “mousse” has lost volatile components and mixed with seawater and organic matter
– Tarballs form as oil weathers further, becoming crusty on the outside and gooey inside
2. Health and Safety Plans (HASP)
OSHA regulations require employers to develop detailed Health and Safety Plans for cleanup operations. These HASPs guide daily operations to prevent contamination, injury, and death. Key components include:
– Introduction and key personnel
– Hazard assessment
– Training requirements
– Personal protective equipment (PPE)
– Exposure monitoring and air sampling
– Site control measures
– Decontamination procedures
– Emergency response/contingency plans
– Medical surveillance
Workers should review their employer’s HASP before beginning work at a cleanup site.
3. HAZWOPER Requirements
The Hazardous Waste Operations and Emergency Response (HAZWOPER) standard applies to oil spill response activities. Key provisions include:
– Emergency response operations (paragraph q)
– Post-emergency response cleanup operations (paragraph q(11))
– Specific training and control measures for hazardous waste sites
Marine oil spill cleanup must comply with HAZWOPER provisions while following National Oil and Hazardous Substance Pollution Contingency Plan regulations.
4. Worker Training and Communication
Proper instruction for cleanup workers is essential. Personnel should receive:

Hazard Communication training is required for oil and hazardous materials workers may encounter. Material Safety Data Sheets (MSDS) must be available, and workers should understand warning labels like NFPA 704M on chemical containers.
5. Personal Protective Equipment (PPE)
PPE requirements depend on the work site’s program and assigned tasks. Common PPE includes:
– Level D modified clothing: Protective pants, boots, disposable gloves, life jackets
– Respirators: From N-95 to Powered Air Purifying Respirators (PAPR) in some cases
– Eye protection: Safety glasses with side shields or goggles
– Hearing protection for noisy environments
Workers must be trained in proper PPE use, including inspection, donning/doffing, and limitations. Only use undamaged PPE that fits correctly and is appropriate for the hazard.
6. Chemical Hazards and Exposure Routes
Oil spill cleanup involves exposure risks to various chemicals:
– Crude oil components (e.g., benzene, toluene, xylene)
– Weathered crude oil
– Dispersants (e.g., COREXIT products)
– Bioremediation agents
– Combustion products from controlled burning
Chemicals can enter the body through:
– Skin contact/absorption
– Inhalation
– Ingestion
– Injection (via cuts or punctures)
Understanding these exposure routes helps workers take appropriate precautions.
7. Decontamination Procedures
Proper decontamination is crucial to prevent spreading contamination and protect worker health. Key aspects include:
– Primary decontamination in the Contamination Reduction Zone
– Secondary decontamination for tools and equipment
– Emergency decontamination procedures
– Proper PPE removal sequence
– Thorough hand and face washing
Follow employer-specified decontamination procedures outlined in the HASP.
8. Heat Stress Prevention
Heat-related illnesses are a significant risk in oil spill cleanup operations. Workers should be aware of:
– Heat rash, heat stress, heat exhaustion, and heat stroke symptoms
– Factors increasing heat hazards (high temperature/humidity, direct sun, physical exertion, PPE use)
– Preventive measures:
– Appropriate work/rest cycles
– Gradual acclimatization to heat
– Proper hydration (small amounts of water frequently)
– Use of cooling equipment and shaded rest areas
– Special precautions for at-risk individuals (e.g., those with certain medical conditions or taking specific medications)
9. Physical Hazards and Safety Measures
Oil spill cleanup environments present various physical hazards:
– Slips, trips, and falls on oily surfaces
– Drowning risks when working near water
– Eye injuries from dust, debris, or chemical splashes
– Noise exposure from equipment
