Buying Guide: Key Purchase Considerations
- Material durability: Choose signs and barricades made for indoor/outdoor use based on site exposure. Aluminum offers excellent rust resistance for outdoor installations, while vinyl and rigid plastic can be cost-effective for temporary or interior use.
- Visibility and size: Larger signs (e.g., 24″ x 18″) provide higher visibility in busy areas, while smaller decals work well for close-up warnings on equipment or doors. Ensure fonts and symbols are legible from a distance appropriate for the site.
- Compliance alignment: Verify that the messaging adheres to OSHA or ANSI standards relevant to your jurisdiction and work environment. Clear access restrictions and hazard warnings reduce liability.
- Installation and mounting: Look for pre-drilled holes and compatible mounting options. Consider the surface material (metal, wood, concrete) and whether temporary adhesive decals are preferable to drilled mounting.
- Reuse and durability: For evolving sites, choose signs that can be relocated or redesigned easily. Reusable rigid plastic signs or decals with residue-free removal are advantageous in dynamic workplaces.
- Scope of warnings: Use a mix of notices (authorized personnel only, freight-only, danger) to cover all restricted areas around elevator machinery, equipment rooms, and mechanical spaces.
Comparative Considerations
- Material trade-offs: Aluminum signs resist rust and weathering, ideal for outdoor placements, while vinyl decals offer flexibility and lower cost for interior or temporary use. Rigid plastic signs balance portability with durability for lightweight zones.
- Size versus impact: Larger signs maximize visibility in warehouse aisles or loading areas, whereas smaller decals suit control panels or interior doors where space is limited.
- Longevity versus cost: Higher upfront cost signs (aluminum, heavy-duty) typically provide longer service life, reducing replacement frequency in demanding environments.
