UNIGUARD / SAFETY & COMPLIANCE
Guarding starts with
the right application.
Understand the standards, installation considerations, and product limitations that inform your machine guarding decisions.
Fit. Secure. Inspect.
A guard must suit the equipment, its hazards, and the way people operate and maintain it.
REFERENCE LIBRARY
Standards to review for your application
Applicable requirements depend on the equipment, workplace, and jurisdiction. Use these sources alongside the selected guard’s instructions and your site’s machinery risk assessment.
OSHA
General machine guarding
29 CFR 1910.212 addresses guarding against machine hazards, including rotating parts and points of operation.
OSHA
Power-transmission equipment
29 CFR 1910.219 covers mechanical power-transmission equipment such as shafts, pulleys, belts, and couplings.
ANSI B11
Safeguarding & risk reduction
ANSI B11.19-2019 (R2024) addresses performance requirements for safeguarding and other risk-reduction measures. Consult the standard for the applicable requirements.
ANSI Z535
Safety colors & product labels
ANSI Z535.1 addresses safety colors; ANSI Z535.4 addresses product safety signs and labels. Safety communication complements the physical guard.
MSHA
Moving parts at mine sites
MSHA requirements vary by mining operation. For metal and nonmetal surface mines, 30 CFR 56.14107 addresses guarding of moving machine parts.

SELECTION & INSTALLATION
Review the complete guarding application
Load capacity, opening dimensions, fasteners, access covers, and safety colors must be checked against the applicable requirements and the selected product. A single specification should not be assumed to cover every machine.
Prevent access to moving parts
Check reach-through, reach-over, reach-under, and reach-around access to the hazard. Select guard openings and clearances for the specific application.
Confirm strength and materials
Confirm the required strength, mounting support, environmental compatibility, and product specifications with Uniguard before selection.
Secure the guard
Use the specified mounting hardware and fastening method. Follow the installation instructions and applicable requirements for removal and access.
Plan inspection and servicing
Choose appropriate inspection windows or access features. Follow the site’s energy-control procedures whenever servicing exposes personnel to hazardous motion.
Make warnings visible
Keep product safety labels legible and visible. Select safety colors and labels according to the applicable standard and site requirements.
Inspect the installed system
Check for damage, loose fasteners, interference, and changes to equipment or access. A compliant installation requires more than selecting a guard by name.
PRODUCT LIMITATIONS
Important information before use
Review these Uniguard product notices when evaluating an application.
Not a ballistic shield
Uniguards are not a Ballistic Shield The UniGuard Coupling or V-Belt guard is designed as a safety device, when used during normal operation and when properly installed and positioned, to prevent fingers, hands, arms, and clothing from contacting the rotating coupling or V-Belt Drive. The guard is not intended to be a containment shell in the event of catastrophic failure of the coupling inside the guard. The guard is not designed as a ballistic shield. Although the guards are very robust, its sole purpose is to prevent human contact in areas with potential hazard from rotating couplings or V-Belts drives.
Static discharge & explosion-proof areas
Uniguard does not recommend these guards for explosion-proof areas.
The UniGuard Coupling or V-Belt guard is designed as a safety device, when used during normal operation and when properly installed and positioned; to prevent fingers, hands, arms, and clothing from contacting the rotating/moving components. These Guards are made of a corrosion resistant engineered plastic material which is non-conductive. The materials which make up the guards do not create sparks when impacted by a striking object. They do not readily conduct electricity, so a static build up is conceivable. Thousands of these guards have been sold into various applications and to date we have never received any indication of a static discharge issue. There is no possible way to test every possible coupling/V-belt drive combination or other conditions which could lead to a static discharge. We do not recommend the use of the UniGuard machine guard in Explosion Proof areas simply as an untested precaution, not due to any known concerns.
