Apparatus (1, 11, 21, 31) is provided for monitoring whether an operator working at height on a platform (121, 131) of a Mobile Elevated Work Platform (MEWP) has properly anchored his safety harness (41) and lanyard (43, 52, 61, 71) to the platform (121, 131). The apparatus (1, 11, 21, 31) is mounted to an anchor point (126, 127, 135) on the platform (121, 131). and has an aperture (6, 26, 33A, 33B) through which a connector such as a carabiner, snap-hook or the like (23, 45, 51, 68, 81, 91, 101) may be passed to connect the lanyard (43, 52, 61, 71) with the apparatus (1, 11, 21, 31). Electrical detectors (7) or switch arrangements (14, 27, 32) register the presence of the connector (23, 45, 51, 68, 81, 91, 101) within the aperture (6, 26, 33A, 33B), and send a signal to a lamp (28) or audible alerting means to indicate whether the operator is safely anchored. The signal can also be used to operate a control switch within a control panel (128, 138) on the platform (121, 131) to prevent operation of the control panel (128, 138) to move the platform (121, 131). The apparatus comprises cover means (3) enclosing the aperture means when closed and openable to provide access to the aperture means , the cover means (3) being connected to the control switch means which acts to prevent operation of the control means (128, 138) when the cover means (3) is closed.
