Published by SALUSSafe Operating Temperature Limits for Workers =============================================
This document outlines the maximum safe operating temperature limits for workers, based on ambient air temperature, to prevent heat stress and ensure workplace safety. It is important to consider these limits in conjunction with other factors such as humidity, workload, and individual worker characteristics.
Ambient Air Temperature Limits
- No operation should occur above an ambient temperature of 120° F (49°C).
- Prolonged operation in ambient air temperatures of 100° F (38° C) or above is not recommended.
Considerations for Hydraulic Systems
Machine operation using non-JLG approved hydraulic fluids or operation outside of the temperature boundaries outlined in the 'Hydraulic Fluid Operation Chart' may result in premature wear or damage to components of the hydraulic system. [2]
Recommendations
- For prolonged operation in high-temperature ranges, the addition of a hydraulic oil-cooler is highly recommended. Consult JLG service for appropriate cooler selection.
- In certain temperature ranges, the use of hydraulic system heating aids may be necessary. Consult JLG service for recommendations.
Disclaimer
The recommendations provided are for ambient temperatures consistently within the shown limits and assume values at sea level. [1]
