Human Factors Focus on Warnings, Part l: Labels, Signs, and Tags

TASA ID: 568

Failure to warn has become a common cause of action in products liability and tort litigation. Over the past 15 years, much scientific research has been conducted on the subjects of warning design and effectiveness.  As discussed here, a warning is a label, sign, or tag used to communicate hazard information. (Note: Part II, a sequel, will discuss visual and auditory warning devices and alarms.)  The purpose of a warning is to modify human behavior and ensure safety compliance, i.e. to give the worker or user an opportunity to avoid harm.

Roofing Construction Toxicity and Flammability Hazards

TASA ID: 3404

In order to reduce energy costs in roofing construction, contractors install cool roofs1 aka Single-Ply Roofing, as estimated by Bob Craig in EDC Magazine, "The majority of new roofing is a white single-ply membrane, either TPO (thermoplastic polyolefin) or PVC (polyvinyl chloride). This is due mostly to new energy codes that require reflective roofing to reduce heat absorption into the structure.”
