Mercury Thermometer Alternatives: Verification Methods for Alternative Thermometers The steam point is not as commonly used as the ice point, but it provides a good method to verify thermometers at a second temperature. In this method, you create steam by boiling water in a beaker. As the steam rises, it will condense on a thermometer that is colder than the boiling point of the water. Insert the calibrated and test thermometers so that the tips of the probes are 10 cm to 15 cm (approximately 4 in. to 6 in.) below the surface of the water. ( 2 If a thermometer probe is very short, immerse the probe as deeply as you can without getting water in the wiring.). 3  Wait 5 min.

- Jefferson Lab considers forklift attachments and lifting devices to be material handling equipment. A forklift attachment is a modification or addition to a forklift that affects its capacity, stability, or safe operation. Lifting devices are used for lifting heavy loads, and when maintained for use with a forklift, do not affect the capacity or safe operation of the truck.

- According to this law, as pressure on the gas increases, the volume of space that the gas occupies will decrease. By squeezing the bottle the pressure on the air inside the medicine dropper is increased as water fills the dropper. The dropper becomes heavier and sinks.ollapsing Metal Can (Boyle’s Law) Description: A metal can is crushed when immersed in cold water. Materials: Empty soda can Beaker Ice water Bunsen burner Procedure: Add 15 mL of water to aluminum can and bring to a vigorous boil. Quickly invert the can and submerge it into the beaker filled with ice.

- Take temperatures of holding units by placing a calibrated thermometer in the coolest part of a hot holding unit or warmest part of a cold holding unit. For hot-held foods: Verify that the air/water temperature of any unit is at 135 ºF or above before use. Reheat foods in accordance with the Reheating for Hot Holding SOP. All hot potentially hazardous foods should be 135 ºF or above before placing the food out for display or service. Take the internal temperature of food before placing it on a steam table or in a hot holding unit and at least every 2 hours thereafter. For cold foods held for service: Verify that the air/water temperature of any unit is at 41 ºF or below before use. Chill foods, if applicable, in accordance with the Cooling SOP. All cold potentially hazardous foods should be 41 ºF or below before placing the food out for display or service. Take the internal temperature of the food before placing it onto any salad bar, display cooler, or cold serving line and at least every 2 hours thereafter.
