Lead on​​ the Jo​b

Most adults with ​lead in their bodies are exposed to lead on the job. Lead can cause serious and permanent health problems.​ Even low levels of lead in the body can cause damage. It is important for workers and employers to do everything they can to lower the amount of lead in the workplace.

​These jobs, hobbies, and other sources c​an expose you t​o lead.​​​​


How does lead get in the​ body?

There are two main ways to get lead in your body:

  • Breathing in lead dust, mist, or fumes.
  • Swallowing lead that gets on hands, food, cigarettes, or other things that you put in your mouth.

How much lead is in your blood​?

A blood test will measure how much lead is in your blood. If you are exposed to lead at work, your employer may be required to have your blood lead level (BLL) tested.

You can reduce your exposure to lead at work​

How to Lower Your Blood Lead Level

The best way to lower your BLL is to reduce or stop your exposure to lead at work. This gives your body time to clear lead from your blood.

Medic​​al Removal Protection​

Lead in blood is measured in micrograms per deciliter (µg/dL​). When a worker has one BLL test at or above 30 µg/dL, or two BLL tests at or above 20 µg/dL taken one month apart, the employer is required to transfer that worker to a job free from lead exposure, or take the worker off the job. The worker must stay away from lead work until the worker's BLL falls to 15 µg/dL or lower in two BLL tests taken 30 days apart. Medical Removal Protection is ordered by a doctor. Workers on Medical Removal Protection receive their full salary and benefits. ā€‹

​Your employer is required by law to protect you at work

If your employer is not protecting you from exposure to lead at work, contact your union representative or ā€‹ā€‹your local Cal OSHA Enforcement Office​.​​​​​
