Iklim Kerja (Work Climate) under Indonesia's Permenaker 5/2018

Under Article 1 point 16 of Permenaker Number 5 of 2018 on Occupational Safety. Furthermore, Health in the Work Environment, Iklim Kerja (Work Climate) is the combination of temperature, humidity, air movement speed. In addition, Radiant heat assessed together with the heat generated by the worker's body due to work activities. Its scope covers both heat stress (tekanan panas) and cold stress (tekanan dingin).

Legal Classification and Threshold Limit Values

Work climate is classified under Physical Factors (Faktor Fisika), alongside noise, vibration, radio or microwave radiation, ultraviolet rays. In addition, Static magnetic fields (Article 1 point 11. Article 8(1)). Employers and/or workplace managers must control physical factors so they remain below the Threshold Limit Value (Nilai Ambang Batas or NAB) (Articles 2 and 3(a)). Specific NAB figures are listed in the Annex of Permenaker 5/2018 (Article 8(2)). The metric used for hot work climates is the Wet Bulb Globe Temperature Index (Indeks Suhu Basah dan Bola or ISBB) (Article 1 point 17).

When Measurement and Control Are Mandatory

Workplaces with heat stress hazards (heat sources and/or inadequate ventilation) or cold stress hazards (cold sources and/or cold operational requirements) must measure. Furthermore, Control their work climate (Article 9(1)-(3)). If measurements exceed the NAB or standard, employers must implement controls such as eliminating the heat or cold source. Substituting equipment or processes, isolating exposure, providing ventilation. Furthermore, Drinking water, limiting exposure duration, and supplying appropriate work clothing and personal protective equipment (Article 9(4)-(5)).

Measurement and control must be carried out by certified OSH Work Environment personnel (Article 45(1)). With external periodic testing conducted at least once a year or according to risk assessment (Article 62(1)).
