Abstract During injection moulding, thermoplastics release more or less toxic pyrolysis products during heating. This well-illustrated booklet provides several practical solutions to the problem of installing exhaust hoods, thus providing exhaust ventilation of the toxic gases. Contents: attachment of the hood to the outside of the machine; lessons drawn from earlier tests; configuration of exhaust hoods and ducts for machines of different injection rates; alternative solutions for machines of unusual dimensions; evaluation of exhaust efficiency using a tracer gas; adaptation of purifying filters to the rate of exhaust gas flow.
