National Occupational Safety and Health Advisory Board membership rules cover appointment, resignation, disqualification, removal, and travelling allowance. Provision is made for the constitution and working of the National Occupational Safety and Health Advisory Board by prescribing the appointment, meeting, resignation, vacancy, disqualification, removal and travelling allowance arrangements for its members. Members specified in the relevant clauses of the parent Act are to be appointed by the Central Government through notification, and the Board may meet whenever required to perform its statutory functions. Non-ex officio members may resign by written notice to the Chairperson, and the vacancy arises on acceptance of the resignation by the Central Government or on expiry of thirty days from receipt of the notice, whichever is earlier. A non-ex officio member who fails to attend three consecutive meetings without sanctioned leave ceases to be a member, subject to the Central Government's power to direct otherwise on sufficient cause being shown.
