Stack sampling and source evaluation exposes DEP officials and consultants to potential safety hazards in the field. Ensuring the safety of all field personnel at facilities is an issue that the EMS takes very seriously.

To insure the safety of all field personnel, stack sampling platforms, both permanent and temporary, and access ways leading to and from the platforms or testing locations, must be designed and erected in such a manner as to conform to published safety laws and regulations. If the EMS observer feels the sampling location is unsafe for any reason, the test will be postponed at his/her discretion.

A short list of safety concerns that could result in a test cancellation is as follows. This list is by no means all inclusive.

• Improper scaffold erection and tie off.
• Corroded and/or structurally compromised surfaces.
• Unsafe, inappropriate or nonexistent but necessary climbing equipment.
• Unsecured electrical hazards.
• Dangerously icy, wet, or hot surfaces.
• High winds.
