 |
Safety/Work Area – active laboratory space; enter with care; do not use these spaces as traffic areas. |
 |
Physical Hazard Area – this area contains a physical hazard, entry by laboratory staff only (yellow cones are equivalent to yellow lines). |
 |
Clean Area – enter area only if authorized by lab staff. Enter only with clean clothes and shoes, and do not bring soiled tools into space. |
 |
Fire Safety Area – this area either contains fire equipment or is an egress route for the laboratory, obstructing a fire area in any way is a violation of New York City Fire Code. |
Audiovisual Warnings
Carleton Lab is equipped with an audiovisual warning system that advises persons present in the lab of potential hazards.
 |
Amber Strobe – test in progress (as described on poster below strobe), enter area only with express permission of lab staff. |

|
 |
Bell - fire alarm, evacuate building immediately, close all doors on the way out. Important: The Engineering Terrace building is equipped with a NYC Code Fire Alarm System; this system will only sound two sets of four bell rings. The fact that the system does not continue ringing does not mean that the fire alarm is over. All personnel MUST evacuate the lab once the fire bell sounds. |
Forklift Safety
- In the lab pedestrians must yield to the forklift. Due to the limited line of sight of the forklift operator in many loading and lifting situations, you must assume that the forklift operator cannot see you.
- Never walk directly in front of or behind the forklift when it is in motion.
Crane Safety
The lab is equipped with a number of gantry cranes. Be aware of their presence at all times. The hi-bay area contains three trambeam cranes that can move within the entire hi-bay space.
- Never step under a crane, be it loaded or unloaded.
- Always look up and check for position of cranes before entering the high-bay area.
The lab also contains a number of removable floor panels. Be aware of these when you are walking. Never cross an area that is cordoned off with yellow cones. This is a warning that hazards lie beyond this point. Ask the lab staff for a safe path in case a normal route is obstructed.
Machine Safety
Active machinery should be approached only with the permission of the operator of the machine. Eye and ear protection must be worn, whenever appropriate (and warning provided on machine).
Only authorized persons are allowed to use the machinery in the laboratory and in the machine shop. Machines may be used only by staff and students who have been properly trained by the lab personnel.
