This Standard provides the means to determine the minimum distances from the sensing or actuating devices of protective equipment to a danger zone. The safety distances are based upon values for hand or arm approach speeds and the response time for the machine.These specific devices are - (a) trip devices as defined in AS 4024.1201 (specifically electro-sensitive protective equipment, pressure sensitive mats), including those used additionally to initiate operation; and(b) two-hand control devices as defined in AS 4024.1201.NOTES:1 For the purposes of this Standard, hold-to-run controls, which are designed to be actuated with one hand, are not considered to be protective equipment.2 Electro-sensitive protective equipment is a forms a family of trip devices which includes active opti-electronic protective devices (AOPD). This Standard does not apply to protective equipment which is intended to be moved, without tools, nearer to the danger zone than the calculated distance, e.g. pendant two-hand control devices.The minimum distances derived from this Standard do not apply to protective equipment used to detect the presence of persons within an area already protected by a guard or electro-sensitive protective equipment.
