Best Practice Tips

OSHA1 requires the employer to ensure that:

  • The equipment is equipped with a commercially available shroud or cowling with a dust collection system that provides at least the minimum air flow required by the manufacturer
  • The shroud or cowling is intact and installed in accordance with the manufacturer’s instructions
  • The hose connecting the tool to the vacuum is intact and without kinks or tight bends
  • The filter(s) on the vacuum are cleaned or changed in accordance with the manufacturer’s instructions
  • The dust collection bags are emptied to avoid overfilling
  • A HEPA-filtered vacuum is used when cleaning holes; compressed air can be used in conjunction with a HEPA-filtered vacuum or hole cleaning kit designed for use with compressed air
  • Additional exhaust is provided as needed to minimize the accumulation of visible airborne dust when operating indoors or in an enclosed space (area where airborne dust can build up)

Other tips:

  • Check the air flow rate to ensure it is equal to or greater than recommended by the manufacturer
  • Visually inspect the drill, hood (shroud or cowl) and the dust collection system to ensure they are properly connected
  • Visually inspect the drill, hood (shroud or cowl) and the dust collection system for missing or damaged parts
  • Check the drill, hood (shroud or cowl), and dust collection system regularly to ensure the system is operating so that no visible dust2 is emitted from the process once the drill has entered the substrate (material)
  • Check and replace the filter and empty the dust collection unit, and use filters and collection bags for collecting silica dust
  • If applicable, regularly check the automatic filter cleaning system to ensure it is operating properly to maintain maximum air flow and suction power and can be used in conjunction with the HEPA filter

Driving in the Rain Safety

Water on the roadway becomes a lubricant that makes road surfaces slick. It’s also said that oil and dust on the road can make the road surface even slicker. Combined with high speeds, wet roads become deadly. It takes diligence on the part of the driver to stay safe during rainy drives. Reduce vehicle speeds. Scan ahead. Wear your seat belt. Reduce distractions. Focus on the road ahead. Review these safety tips with drivers in your organization.

11 Worksafe Tips For Driving Safely In The Rain

  1. Everyone in the vehicle should wear their seat belt.
  2. Leave early and plan a route that avoids traffic congestion.
  3. Its Missouri law that whenever wipers are used, headlights must be on.
  4. Reduce vehicle speeds – avoid hydroplaning.
    • Hydroplaning means that the vehicles’ tires actually travel on top of a water layer instead of contacting the road surface.
    • Hydroplaning can cause the vehicle to spin out of control, much like it is on ice.
    • If hydroplaning occurs, keep the steering wheel straight and let off of the gas pedal.
    • Gently apply brakes – don’t lock them up!
  5. Avoid a collision by scanning ahead for:
    • Accidents
    • Water over the road
    • Stopped or slowed traffic
  6. Reduce distractions like:
    • Cell phone use
    • Eating, drinking, grooming
    • Manipulating vehicle systems
    • GPS
    • Changing CDs or radio stations
  7. Focus on the road ahead and give driving full concentration during the rain.
  8. Don’t use cruise control – the vehicle may actually accelerate when hydroplaning occurs! Use your headlights.
  9. If rain becomes heavy, pull off of the roadway into a parking lot or side street to wait it out.
  10. Never drive through rushing water over the roadway.
  11. Water can easily pick up and move an automobile!

  • Are the materials I am using safe, and do I need additional personal protective equipment such as: safety glasses, gloves, hard hat, respirator, etc.?
  • Is there a safer way to accomplish the task?
  • Are all necessary equipment guards in place?
  • Are written procedures such as lockout/tagout being followed?
