<br /> APPROVED BY:
<br /> (Project Manager or
<br /> Project Director,at a
<br /> minimum)
<br /> *At a minimum,Corp.H&S must review/approve the THA review when Geosyntec staff will encounter"high hazards/high risks,"or perform critical tasks,such as(but not limited to):
<br /> Climb ladders to heights>10' Implement lockout/tagout controls Instrument monitoring for critical exposure risks
<br /> Use a personal fall apparatus Enter a trench/excavation>5'deep Wear a respirator
<br /> Self-perform tasks classified as construction labor Work near heavy equipment or crane Presence of"high-risk"contaminant(s)
<br /> Climb ladders to heights>10' Function as a construction"Competent Person' Sustained exposure to wildfire smoke AQIPM 2.5>150
<br /> Tow a trailer on roadway Operate a pneumatic or powder-actuated tool Enter EZ/CRZ during HAZWOPER cleanup activities
<br /> Oversee a hot-work permit system Electrical testing&maintenance(<50 V excluded) Exposure to radioactive isotopes(a,R,y)
<br /> Enter a permit-required confined space Work at height near overhead electrical utility lines Onsite risk of emergency chemical spill
<br /> Operate a UTV/ATV,aerial lift or fork-lift Derive action levels for VOCs or toxic dusts Applicability of Chemical Anti-Terrorism Standards
<br /> Corporate H&S must also be consulted when Geosyntec subcontractors(under Geosyntec's oversight)perform high hazard/high risk work(such as demolition,blasting,crane lifts,
<br /> confined space entry,testing/maintenance of electrical systems,lockout/tagout,HAZWOPER cleanup activities),OR when supplemental written H&S programs are required for a project
<br /> (such as Electrical Safety Program,Lockout Program,Confined Space Entry Program,Emergency Response Plan),OR when a written safety plan must be submitted to a public agency.
<br /> Consultation with Corp.H&S is encouraged for all questions/concerns regarding worker safety,regulatory compliance,risk/liability aspects,or project-specific safety requirements.
<br /> Geosyntec H&S Procedure:For more information,see HS-204-Work-Specific Hazard and Risk Assessment,Written Safety Plans.
