Pine processionary Pine processionary The pine processionary ("Thaumetopoea pityocampa") is a moth of the family Thaumetopoeidae. Sometimes placed in the genus "Traumatocampa", it is one of the most destructive species to pines and cedars in Central Asia, North Africa and the countries of southern Europe. The urticating hairs of the caterpillar larvae cause harmful reactions in humans and other mammals. The species is notable for the behaviour of its caterpillars, which overwinter in tent-like nests high in pine trees, and which proceed through the woods in nose-to-tail columns, protected by their severely irritating hairs, as described by the French entomologist Jean-Henri Fabre.
Health Hazard Evaluation Program mid-sized business owners can request an OSHA consultation, and owners are required to correct identified hazards. In contrast, employers, employees, and unions from any sized business can request an HHE, and employers are not required to follow HHE program recommendations. The HHE Program provides technical assistance during federal emergencies. Staff are trained to respond to a natural disasters and biological, chemical, explosive, and radiological events. The HHE Program provided protection to emergency response workers in the September 11 attacks, anthrax attacks, Hurricane Katrina, Deepwater Horizon oil spill, and the Ebola epidemic.
