It's important all people...
- Foremen, superintendents, and
- Project managers and those involved in the proposal and planning phases of construction that may involve silica-containing materials.
- What the health hazards are
- When and where silica-containing materials pose a concern, and
- How to eliminate, or at least control the exposure hazard.
Make sure they clearly understand the:
Health Hazards, including
- Lung cancer
- Chronic obstructive pulmonary (lung) disease (COPD) and decreased lung function.
Exposure Controls, including
- Methods used by the employer to control employee' exposures to airborne dust, such as
- Wet cutting
- Local exhaust ventilation systems
- Isolation of the process from the operator and surrounding employees by means of distance, enclosure or other method, as applicable
- Work practices
- Proper use and maintenance of dust reduction systems, including the safe handling and disposal of collected waste materials
- The importance of good personal hygiene and housekeeping practices when working with or around dust containing crystalline silica, including:
- Ensuring that hands, arms, face, and any exposed parts of the body are thoroughly washed before eating, or leaving the worksite.
- Not smoking tobacco products.
- Using appropriate methods to clean employees' own clothes
- Making sure that protective clothing worn to prevent employees' own clothes from getting contaminated is safely discarded (before leaving the worksite) in a manner that does not spread contamination.
In addition to what employees are trained on, supervision and management needs to also be able to:
- Identify tasks employees will perform that may result in employee exposure to silica containing dust, and
- Determine procedures for implementation of the measures used by the employer to reduce the exposure to concrete or masonry dust
NOTE: For activities falling within the scope of Section 1530.1, all of the above must be addressed with employees and supervision on at least an annual basis.
