For outdoor assembly signs, durable, rust-proof aluminum is the best choice for longevity. For enhanced visibility, especially in low-light conditions or during adverse weather, using engineer-grade reflective sheeting on the aluminum is ideal. This ensures the sign can be seen from a distance, day or night. A non-reflective aluminum sign like our Emergency Assembly Area Sign is a great durable option, and you can explore various reflective options on our custom reflective signs" page.

Assembly signs should be checked during regular facility safety audits, at least annually, to ensure they remain clean, legible, and unobstructed. Inspections should check for fading, damage, or any new environmental elements (like plant growth or new construction) that might block their visibility. Maintaining safety signage is part of an employer's general duty to provide a safe workplace under OSHA guidelines. A durable sign like our Evacuation Assembly Area Sign is built to last but should still be part of a regular inspection schedule.

A post-mounted sign is designed with pre-drilled holes to be attached to a pole or post in an open field or parking lot. This is the most effective way to display a muster point sign because it creates a clear, elevated landmark that is visible from 360 degrees, which is essential for guiding evacuees in a large, open space. A sign like our Emergency Muster Area Safety Sign is a perfect example of a sign designed for post mounting.

The size of the sign depends on the viewing distance. Larger, more visible signs are needed for large facilities, parking lots, or campuses where people will be looking for the sign from hundreds of feet away. A smaller sign may suffice for an assembly area just outside a small building. ANSI and OSHA standards provide guidelines on character height and sign size for legibility at a distance. For a large, highly visible option, consider our Emergency Evacuation Gathering Point Sign. You can also learn more by watching our video on how big your sign should be.
