Medium-Pressure Flushing (On Shore)

The information and recommendations in this fact sheet may change as this oil response and cleanup work continues.
This fact sheet will be revised as needed so make sure you have the latest version.
August 23, 2010

What Is This Job?

Workers use medium-pressure water spray to flush oil from rocks, boulders, cobbles, man-made structures, and plants. (Medium pressure is between 100 and 3,000 pounds per square inch, or psi.) The oil is pushed into areas where it can be collected.

What Dangers Has OSHA Found For This Task?

OSHA has closely watched workers doing oil spill work and has run many tests to see if there are harmful substances in the air. The major risks that OSHA has found for this job are:

  • Heat stress is a very serious risk for workers in the Gulf. It can cause a lot of different problems, from just feeling dizzy or sick to your stomach to fainting and death.
    • Heat stroke is a medical emergency. It causes confusion and you may have seizures (fits), pass out, or even die - Call for medical help right away and begin cooling the person (move them to the shade or air conditioning, douse with cool water, and fan them) while waiting!
    • Heat stress can give you a headache and make you dizzy and very tired. You may pass out, feel sick to your stomach, throw up, and have muscle cramps. Get into the shade and drink water right away! Notify a supervisor and have someone stay with you/coworker because this could become heat stroke
  • Pressurized water can damage eyes and bruise skin
  • Weathered oil can cause rashes on bare skin
  • Noise at loud levels or certain pitches can cause hearing problems for a short time or can damage your ability to hear for the rest of your life
  • Slippery surfaces and tripping over ropes, cords, or hoses can cause you to fall

Other hazards to be aware of:

  • Sunburn and sun poisoning
  • Drowning when working in or over water
  • Back injuries, joint and muscle problems from repeated bending and lifting, or from moving heavy objects being washed
  • Motors, winches, pumps, and other machines with moving parts can strike or crush a worker

What Must My Employer Do To Protect Me?

Employers must provide their workers with a safe workplace. You should report any unsafe working conditions, injuries, or illnesses to your supervisor or safety coordinator right away. For the ongoing oil response and cleanup operations, your employer must have a site safety plan for where you work and share it with you. The plan must include:

  1. The training you need to safely do this task.
  2. The work practices you need to use to avoid getting hurt or sick.
  3. The protective clothing and equipment you need when doing this job.
  4. How to report any health and safety hazards, illnesses and injuries.

Your employer must provide you the safety clothing and equipment you need to do your job safely and replace it if it wears out.

What Training Do I Need To Do This Job Safely?

Workers doing this task must take a four-hour class on shoreline spilled oil response (Module 3). Supervisors must have additional hazardous waste operations training.

What Work Practices Do I Need To Use?

  • Follow the work-and-rest schedule for your work site based on the weather and the time of day [for example, 20 minutes of work and then 40 minutes of rest (in shade, if possible) each hour].
  • Drink water often throughout the day.
  • Always wear your protective clothing and equipment properly and ask for new equipment if it is worn out and no longer protects you.
  • Decontaminate and remove your protective clothing before breaks and at the end of your work shift.
  • Put used protective clothing and other equipment in the proper place.
  • Point the water stream away from you and from others as you work. Try to work upwind of the over spray. Always work from the top down.
  • Follow the user's manual instructions for inspecting, using, and refueling the pressure washer.
  • Use insect repellent with DEET.
  • Apply sunscreen often to exposed skin.
  • Use lifting equipment and get others to help you when moving heavy objects.
  • Don't put your hands in holes or under objects until you check for snakes, insects, or other animals.
  • Don't use broken or damaged tools. Turn them into your supervisor so no one else uses them.
  • Keep walkways and paths clear of electrical cords, cable, ropes, and other tripping hazards.
  • Wash your hands with soap and clean water before eating, drinking, smoking, using a toilet, or handling a phone or other personal items.

What Safety Clothing and Equipment Must My Employer Provide (Free of Cost)?

If you are doing this job, then you need:
Barrier Suit for Solids and Breathable Barrier Suit for Solids and Light Splash Breathable barrier suit for solids and and light splashes Tight-knit, coated clothing that keeps dirt, grease, grime and light chemical splashes off skin and clothing.
Sun Hat and Sun Screen Sun hat and sun screen Protect you from sunburn and help prevent heat-related illness.
Safety Googles Safety goggles Cover your eyes and nearby skin and protect against dust, splashes, impact and flying objects.
PVC Gloves PVC (polyvinyl chloride, plastic coating) heavy general-duty use gloves For heavy use, thicker PVC gloves (26-40 milliliters) prevent oil, grease and other petroleum products from touching your skin.
Face Shield Face shield Face shields are worn over goggles to provide extra protection from splashes and sprays.

PFD Personal flotation device (PFD) Protects you from drowning. Only required when working on docks, or vessels, or if entering the water or surf.

Do I Need To Wear A Respirator?

OSHA sampling data indicates that using high pressure water on oily booms, equipment, and other surfaces could create oil mist and other chemicals in the air. Because of the way that this task is done, you cannot completely control the level of oil mist and other chemicals by using only the work practices listed and natural ventilation. For these reasons, medium and high pressure washing operations MUST be continually monitored so that your supervisor or safety coordinator can tell you when additional protective equipment, including a respirator, is needed.

The correct respirator for this operation must be at least a P100 DISPOSABLE FILTERING FACE PIECE shown in the picture below:

P100 Disposable Filtering Face Piece

BEFORE you can use a respirator, your employer MUST train you in the proper use of this equipment, and make sure a medical professional says you are physically able to wear a respirator.

How Can OSHA Help Me if My Employer Puts Me at Risk or Does Not Provide Me With the Equipment and Training I Need?

All workers involved in the oil spill response and cleanup have the right to a safe workplace just as they would in any other job. Contact OSHA at 1-800-321-OSHA (6742) if you think your job is unsafe, if you have questions about safety and health or if you have symptoms and want to report them. OSHA keeps your information confidential. You may file a complaint to have OSHA inspect your workplace if you believe that your employer is not following OSHA standards or there are serious hazards.

OSHA Protection From Discrimination If You Raise Safety And Health Concerns

You may also file a complaint if you believe you were fired or in any way retaliated against for raising safety concerns to an employer or for participating in safety and health activities. OSHA protects workers who complain to their employers, OSHA or other government agencies about unsafe or unhealthful working conditions in the workplace or environmental problems. You cannot be transferred, denied a raise, have your hours reduced, be fired, or punished in any other way because you used any right afforded to you under the OSHA Act.

If you have been punished or discriminated against for using your rights, you must file a complaint with OSHA within 30 days of the alleged reprisal for most complaints. No form is required, but you must send a letter or call your local Area Office to report the discrimination (within 30 days of the alleged discrimination). You can also call the 1-800 321-0SHA (6742) and they will connect you to your area office.
