Vehicle noise
3. Social and psychological problems on board. Invited specialist will present practical solutions to ship ergonomics problems. Collection and systemisation of relevant ergonomics data, and presentation of these in a form easily applicable by the designers of ships and ship equipment,will be stressed. Practitioners, seagoing people and others, will generally be invited to contribute with short communications on research results, practical experiences, special problems, and ideas for solutions of practical problems.
Monitoring behaviour and supervisory control An international symposium under this title will be held at Berchtesgaden, Germany, from 8 - 1 2 March, 1976. Papers are requested (Abstracts by 1 July) on the following topics: emerging man-machine problems in vehicle control, experiment and theory in man-vehicle control, emerging manmachine problems in process control, experiment and theory in process control, and general models of monitoring and supervision. Further information available from: Dr G. Johannsen, Forschungsinstitut fur Anthropotechnik (Research Institute for Human Engineering), 5309 Meckenheim, F.R. Germany.
J. &. S. Sieger Ltd (31, Nuffield Estate, Poole, Dorset), the Model 1650, provides personal safety for workman engaged in areas where the potential of a flammable atmosphere exists. It can be easily carried on a waistbelt or hung by the hook provided in the immediate working environment. The unit is designed to monitor the level of an explosive gas in the range 0-100% of the Lower Explosive Limit (LEL, the lowest concentration at which the gas will ignite). Adjustment is provided to give both visible (flashing light and meter) and audible alarm at a chosen gas concentration. Construction consists of the main body containing the meter, electronics and alarm functions together with a separate re-chargeable battery pack. In addition, an aspirating attachment is available to reach sampling points inaccessible to the basic diffusion unit. This is a snap-on aspirator fitted with a flexible or extendable rigid probe. Sampling is by means of an aspirator bulb with one way valve.
Vehicle seat for children A vehicle seat for two-to-four year old children, the Secursit, consists of four parts: detachable webbing connecting the frame of the seat to the rear anchor points of the car, a tubular frame, a padded all-round shell and a harness. The child is protected on every side. The seat is attached by webbing to the anchor points designed for the rear seat safety belts and the webbing is threaded into the frame. Single strap retention is rejected, since this leads to dangerous twisting of the spinal column at the moment of impact, as is also that of two cruciform straps which would lead to suffocation, and the manufacturer has adopted the harness developed for car racing. This consists of two straps on a sub-abdominal belt, this harness being attached to the frame of the seat and not to the plastic shell, thus preventing any risk of tearing away. The buckle has been designed so that the child can open it himself.
ICI safety code Imperial Chemical Industries Ltd has released to RoSPA for general publication another of its comprehensive safety codes. This latest release is on Lifting Appliances and is intended to give guidance for the safe use of such equipment which should, of course, comply with current statutory requirements concerning design, construction, maintenance and application. It deals with the periodic examination and inspection of lifting appliances, and indicates the policy to be followed to ensure safe operation. It highlights safe practices and the relevant statutory responsibilities. This 8d-page code covers: design and ordering; issue, maintenance and records; application and use; heat treatment; detailed regulations and statutory forms. There is also a short bibliography and an index. Lifting Appliances is available from RoSPA, Royal Oak Centre, Brighton Road, Purley, SurreyCR2 2UR. Price per copy including packing and postage £3.00 (RoSPA members £2.50)
In the event of a severe impact, all the forces are transmitted to the webbing and the tubular frame which folds, absorbing a considerable proportion of the energy. The weight of the harnessed child is taken by the lower part of the frame, the top part of which maintains the seat as a whole in position in the car. Details from: Societe Morellet Guerineau, Boite Postale 11, 49309 Cholet, France.
