    2. The Big Question Who covers the health and safety of public sector workers in Massachusetts???

    3. Private versus Public Sector Workplaces All private sector workplaces in the US are covered by OSHA Standards. Public sector workplaces are only covered by OSHA Standards in certain states (Currently 26 states). Known as “State-plan States”. There are additional States that have adopted some form of OSHA standards at the State level.

    4. Massachusetts Public Sector Safety Massachusetts has not passed a law requiring public sector workers to comply with OSHA standards Mass General Law Chapter 149- DOS and AGs shall determine reasonable means and requirements to prevent injury and illness to municipal workers. (Note-does NOT cover State workers)

    5. Mass General Law Chapter 149 for Municipal/County Workplaces Interpretation by (DOS) – in order to meet the intent of Chapter 149 section 6 OSHA standards or applicable consensus standards should be followed as a minimum for county and municipal workplaces. If you follow OSHA standards or equivalent, you will be in compliance with Chapter 149.

    6. What About State Workers? State employee health and safety is under the jurisdiction of the Personnel Administrator (HRD). DOS is providing assistance to HRD for state employee health and safety through an agency partnership agreement, including: Trainings focused on high hazard issues On-Site Assessments Outreach and informational materials on important health and safety topics Executive Order 511 requires joint labor/mgt health and safety committees to assess hazards, report findings etc

    7. What does this all mean to me?? Bottom line-Municipalities, counties and State facilities are expected to follow OSHA standards DOS can provide assistance

    8. Key Tank Safety Hazards and applicable OSHA standards Falls from climbing ladder Falls from top of tank Confined space Entry

    9. Falls from Should be protected from falls the ENTIRE time you are climbing tank. Should be able to move from attached ladder climbing device to top of tank without risk of falls. If no guardrails, never work unattached.

    10. Ladder Climbing Fixed ladders -requires cages as minimum over 20 feet. Platforms every 30 feet. Studies have shown cages not effective for falls Should have ladder climbing devices !!

    11. Walking on top of Tank OSHA requires fall protection at elevations over 4 feet (6 feet in construction) Three choices- Best-Guardrails If not- Fall restraint/prevention Fall protection

    12. Guardrail Requirements Railing should be 42 inches Midrail between Toeboard 4 inches high Must withstand 200 pounds presssure Passive System… Does not require workers to tie off etc. Most protective.Passive System… Does not require workers to tie off etc. Most protective.

    13. Fall Prevention/Fall Protection (Fall Restraint)/(Fall Arrest) Need to be sure worker cannot fall more than 6 feet. Shock absorbing lanyards, etc.

    14. Anchorage Points Fall Restraint-keeps worker from edge of tank so cannot fall over edge- requires 1000 lb anchorage point Fall Protection-keeps from falling more than 6 feet below if go over tank edge-Requires 5000 lb anchorage point (recommended) (Note if limiting fall to 2 feet need 3000 lb anchorage point (self retracting lifeline/ropegrab)

    21. Confined Space Entry Rusting is oxidation-uses up oxygen and can create an oxygen deficient environment. Breakdown of organic matter can create toxic environment. Opening hatch and putting head inside tank to inspect is considered a confined space entry Minimum requirement is to air monitor prior to placing head inside tank Must also be attached so cannot fall into the tank. May involve davit arm. Two persons, attendant and entrant.
