Taking Warning Signs Seriously
National Parks Department Negligence Guidelines
What are Warning Signs?
How do Warning Signs work?
- Conventional,
Use standard "Danger" or "Caution" placard. Message text printed in sans serif type.
- Seen,
Place signs where they are easily viewed, yet do not place viewer in harm's way when reading the sign.
- Understood,
Concise message which accurately describes the danger or state the cautionary activity, and,
- Respected
The signs must be in the best possible (like new) condition. They must un-obstructed by vegetation. And, they must be removed when they are no longer applicable.
Most importantly, they must be accurate.
What would happen if a Warning Sign doesn’t satisfy all four elements?
Are there established National Park Service standards to follow?
- OSHA (OSHA 29),
- CFR (29CFR 1910.154), and
- ANSI (ANSI Z35.1-1972).
Those references do not specify what hazards need to be posted.
(See the discussion at the bottom of the page for more OSHA, CFR and ANSI regulations.)
Don’t sign open and obvious hazards, e.g., uneven walking surfaces, loud noises at the airport, etc. Signs such as this will lessen the impact of the important ones.
Do Warning Signs eliminate lawsuits or tort claims?
Failure to post and maintain Warning Signs maybe grounds for a finding of Willful and Malicious Negligence.
Posting and maintaining quality Warning Signs provide a basis for contributory negligence defense. In other words, it can be shown the prudent person was adequately warned of the hazard and injuries resulted from a conscious decision to ignore the Warning Sign.
Other than the safety documents cited above, what guidelines govern Warning Signs text?
- Be Direct (state the hazard, don’t be wishy-washy),
- Be Brief (state the hazard in as few words as possible),
- Be Accurate (don’t overstate or understate the potential hazard or its effects),
- Be Positive (people are less apt to heed signs that begin with, "Don't"),
- Be Seen (put the sign where it is obvious, and keep the foliage cleared away),
- Be Attractive (be as professional as possible),
- Be Legible (if time does not permit a manufactured signs, use your best penmanship),
- Be Proportionate (make the important words big and the modifiers small),
- Be Obvious (avoid cute and touchy-feely – this is serious).
- Maintain Warning Signs to continue their credibility and effectiveness
- Rather than tell what not to do, good Warning Signs tell the safe behavior.
