Abstract In 2007, NIOSH received a confidential employee request for a health hazard evaluation at a metal furniture manufacturing plant. Employees were concerned about exposure to welding fumes and dust from powder painting and grinding operations. During the initial site visit, NIOSH staff met with management and employee representatives, toured the facility, observed work processes and existing engineering controls, observed the use of PPE and interviewed 10 employees. Bulk samples of powder paint were collected for particle sizing and to check for silica and asbestos content. Two of the 10 employees interviewed reported symptoms not related to exposures in the workplace. They described episodic transient shortness of breath that lasted a few minutes and also affected members of their families who were not employees of the plant. Their condition did not improve when they were away from work. Two other employees reported eye and throat irritation. The remaining six employees reported no symptoms. A second survey was conducted to evaluate exposures to welding fumes. No specific cause was identified and threshold limit values were mostly within acceptable levels. A number of recommendations were made concerning the use of paints that do not contain triglycidyl isocyanurate (TGIC), use of welding wire that does not contain manganese, ventilation, personal protection, engineering controls and information of personnel.
