SAFETY FEATURES
4-6.1
Fall Protection. Design equipment so that fall hazards are minimized during
maintenance, repair, and inspection or cleaning. Consider future degradation of
installed fall prevention components in maintenance and inspection activities. Design
should minimize work at heights. Include in a design prevention systems such as
guardrails, catwalks, and platforms. Provide anchorage points compatible with the job
tasks and work environment. Design horizontal cable, vertical rail, cage or I-beam
trolley systems in areas where employees require continuous mobility and where
platforms, handrails, or guardrails are not feasible. Ensure proper test methods are
used to ensure systems are capable of fall prevention functions. References applicable
to fall protection include OSHA 29 CFR 1910 (Subpart F), ANSI Z359.1, and NFPA
101.
4-6.2
Equipment Lockout and Disconnect. Specify or design energy isolation
devices capable of being lockedout. Layout machinery and equipment to ensure safe
access to lockout devices and provide each machine/equipment with independent
disconnects. Specify lockout devices that will hold the energy isolating devices in a
"safe" or "off" position. Ensure equipment and utilities have lockout capability and that
any replacement, major repair, renovation, or modification of equipment will still accept
lockout devices. Design emergency and non-emergency shutoff controls for easy
access and usability. Integrate actuation controls with warning lights and alarms to
prevent personnel exposure to hazards. References applicable to equipment lockout
and disconnect include OSHA 29 CFR 1910.147, ANSI Z244.1, and NFPA 70.
