The NLCSA will send you a reminder letter and a blank Internal Audit instrument approximately 90 days before your Internal Audit is due.  The letter will list the supporting documentation to be included with your audit.  This may include: minutes from recent toolbox meetings; OHS Committee minutes; inspections; hazard assessments; monthly safety summary; maintenance documentation; annual comprehensive hazard assessment; fall protection inspection reports, a copy of the ESRTW program (for Large PRIME assessment employers only), and/or other documentation, as applicable.
