4 Protection Measures
4.1 Overview
If the risk assessment shows that the risk of burns may occur, you should determine whether it is necessary to take protective measures, if necessary, should be determined taking
Which protective measures. In order to reduce or eliminate any risk of burns may occur, protective measures should apply to all products and production
Product standards to be specified.
Under normal circumstances, protective measures can be taken in engineering, management or personnel protection in three areas. As to whether it is necessary to take all protective measures
And take to apply protective measures will depend on the use of the product. Set specific protective measures within the scope of this part of the discussion.
Protective measures or protection of information and product manufacturers can use specially adapted to provide the user with the equipment.
4.2 contact surface protection measures
One of protective measures is to limit the surface temperature of the device burns below the threshold that the surface temperature limits should be determined in the product standard gauge
Burns within a given threshold value or less. In this regard, the manufacturer should take appropriate protective measures, so that the products meet the established temperature limits
Claim.
Surface temperature and the surface temperature of the restrictions established limits only apply to products of some components that are shipped products
The main part of the line is necessary to heat the product will not be considered.
4.3 adjacent surface protection measures
Suitable protective measures include. to limit the product dimension to the smallest area, the use of alternative materials or surface structure and to limit
The possibility of contact with the surface adjacent to and functional surface by taking quarantine measures to reduce the temperature of the conductive or insulating.
Relevant product standard or product manufacturer shall determine the size of the surface of the product features, if necessary, temperature limits and other relevant […]
