What should you do when a tempilstik is not available?

When a tempilstik is not available, the best course of action is to carefully pass your hand near the bearing without touching it. This method allows you to gauge the temperature of the equipment indirectly. By feeling the heat radiating from the bearing, you can assess whether it is operating within acceptable temperature limits. This tactile check serves as a quick and primitive way to monitor conditions when specialized equipment like a tempilstik is not on hand.

Using a thermometer, while it may seem like a reasonable alternative, typically requires direct contact with the surface to get an accurate reading, which may not always be feasible without proper tools. Waiting for a tempilstik to arrive may lead to unnecessary delays in operations, while taking no action could allow potential overheating or malfunctioning to go unchecked, posing safety risks. Therefore, assessing temperature using your hand is the most practical and immediate action under these circumstances.
