WHS policies and procedures including SDSs are an invaluable resource. Consult your safety policy and procedures manuals and SDSs prior to installation/maintenance or troubleshooting to ensure you are working safely.
Operator Manuals are an excellent resource for installation/maintenance or troubleshooting queries.
Safety Bulletins from SafeWork or WorkSafe are also fantastic references.
