Formaldehyde and paraformaldehyde study in funeral homes.

Formaldehyde is a toxic gas and classed as an upper respiratory irritant. The gas possesses distinctive physiological properties causing symptoms familiar to many formaldehyde workers, such as: burning of the eyes, lacrimation, and general irritation of the upper respiratory passages. To demonstrate this toxic action of formaldehyde a study was conducted in embalming rooms of funeral homes to determine the concentration and its effect on the embalmers at this level. The control measures in these establishments were also evaluated and found to be inadequate in some respects. Paraformaldehyde powders were sized and found to contain a respirable fraction. The results of the study show that these workers verified the fact that formaldehyde is an irritant at levels that are below the present Threshold Limit Value.
