Health and Safety Factors. Malononitrile is usually available as a soHdifted melt in plastic-Hned dmms. Remelting has to be done carefully because spontaneous decomposition can occur at elevated temperatures, particularly above 100°C, in the presence of impurities such as alkaHes, ammonium, and 2inc salts. Melting should be carried out by means of a water bath and only shordy before use. Occupational exposure to malononitrile mainly occurs by inhalation of vapors and absorption through the skin. Malononitrile has a recommended workplace exposure limit of 8 mg/m, an LD q (oral, rats) of 13.9 mg/kg, and is classified as slight irritant (skin irritation, rabbits). Transport classification RID/ADR 61, IMDG-Code 6.1, lATA/ICAO 6.1.

The approach to developing metrics for process safety is analogous to those that might be used to assess Occupational Exposure risk. One can cite as well several indices that have been developed as metrics for estimating and ranking the safety of a given process or chemical reaction, such as the DOW fire and explosion index,the Stoessel index ° for hazard assessment and classification of chemical reactions, the Inherent Safety Index, the Prototype Index for Inherent Safety, amongst others. ... 

In clinical chemistry, a great number of components are to be determined. These components may be classified according to their physiological fimction. In occupational toxicology, a division into functional chemical components may be a better classification.

A review is given of the relationships between coatings, regulations and the environment. Mention is made of classification and labelling, the dangerous substances directive, the dangerous preparations directive, market restrictions, occupational exposure limits, and solvent controls. 11 refs.

The life safety features that apply begin with the classification of the building or structure under evaluation. Classification of a building is a combination of hazard of contents and occupancy. 

Occupancy classifications fall into the following categories ... 

Once the occupancy and hazard of contents classifications have been defined, then appropriate life safety design features can be identified. These... 

The intermediate octahedral sheet is normally made up of cations of charge 2 or 3 (Mg, Al, Fe, Fe, or, more rarely, V, Cr, Mn, Co, Ni, Cu, Zn), but in some cases cations of charge 1 (Li) and 4 (Ti) are also found. In the infinite octahedral sheet, formed by the sharing of six corners of each octahedron, there may be full occupancy of all octahedral sites ( trioctahedral micas ) alternatively, one site out of three may be vacant ( dioctahedral micas ). Nevertheless, the primary classification of micas is based on the net charge of the mixed 2 1 layer. In common micas this charge is close to 1, whereas in brittle micas it... 

Serious Injury—The classification for an occupational injury which includes all disabling work injuries and non-disabling work injuries as follows eye injuries requiring treatment by a physician, fractures, injuries requiring hospitalization, loss of consciousness, injuries requiring treatment by a doctor and injuries requiring restriction of motion or work, or assignment to another job. 

A particilarly powerful use of the classification results is in factor analysis. This will help to uncover interrelationships anong the particle types and will provide additional information for source attribution. The results of the factor analysis are also helpful for judging the significance of the cluster analysis, in that if the occupations of two similar particle types are uncorrelated over several samples then this indicates that the particle types and the clusters from which they are derived are significantly different. 

Group 2A = Probably carcinogenic to humans. This classification is not specified for the fuel oils discussed in this profile, nor for exposure to fuel oils by the general population rather, this classification applies only to occupational exposures in petroleum refining.

Repeated skin contact in mice with fuel oils has caused skin cancer, although information is conflicting. The lARC has determined that residual (heavy) fuels and marine diesel fuel are possibly carcinogenic to humans (Group 2B classification). The lARC has also determined that occupational exposure to fuel oils during...
