Safety First
Minimize the
Hazards
The most common reason to access the area below a raised carriage deck is to clean
debris from the pit or hoistway. This is best accomplished using a long handled broom or
rake to avoid entry under the raised carriage deck. Entry under the raised carriage deck
is acceptable only when unavoidable and then only if the proper precautions are taken. It
is the user’s responsibility to ensure that the following conditions be met before allowing
qualified personnel to enter the area under the raised carriage deck.
z
Work must be performed by qualified maintenance technicians.
◊ ASME B20.1 defines a qualified person as “A person who, by possession of
recognized degree or certificate of professional standing or by extensive knowledge,
training, and experience, has successfully demonstrated his/her ability to solve
problems relating to the subject matter and work.”
z
The facility has performed a Risk Assessment per ASME B20.1-2015 5.16
◊
Reference OSHA 3071 for Job Hazard Analysis
◊ Reference CEMA Technical Report 2015-01, ASSE Z590.3, and MIL-STD-882 for
Risk Assessment examples.
z
A proper Lockout/Tagout (LOTO) procedure has been performed on the VRC.
◊ Refer to ANSI/ASSE Z244.1-2003 (R2014), Control of Hazardous Energy —
Lockout/Tagout and Alternative Methods, and OSHA Standard 29 CFR 1910.147,
The Control of Hazardous Energy (Lockout/Tagout).
z
At least two (2) means of support are used to secure the raised platform.
◊
The lifting systems can be used as one means of support provided that no work is
to be done on the hydraulic system or mechanical drive system and an appropriate
LOTO has been performed on the VRC.
◊ Additional means of support include adequately sized maintenance chains,
maintenance pins, DeckLocks, or straps with shackles around the drivebase that
are capable of supporting the weight of the carriage.
