IME Laboratory Safety Guidelines

Flashcards covering key safety guidelines, procedures, apparel requirements, and specific lab hazards for IME laboratories.

What minimum proficiency score must a student achieve on the laboratory safety test to pass?

Students must achieve a proficiency score of $75\%$ or better, with up to three attempts allowed.

What phone number should be dialed from a cell phone to reach campus police directly in an emergency?

Dial 909/869-3070 to reach campus police directly.

Why is calling 911 from a cell phone discouraged in the IME laboratory?

Calling 911 on a cell phone connects to the CHP (California Highway Patrol), which significantly delays the response time.

What approved standard must all safety glasses or goggles meet?

They must meet the ANSI Z87.1 standard.

What is the primary function of gloves when handling hot items in the laboratory?

Gloves are meant to protect the user from accidental contact with hot materials, not to hold or handle hot items directly.

What is the policy regarding independent work in the IME laboratories?

Independent work is currently not permitted in the IME laboratories due to a lack of proper resources.

What are the rules regarding food, drinks, and empty food containers in the laboratory?

Food, drinks, and empty food containers are strictly prohibited from entering the laboratory (including inside backpacks) and cannot be disposed of in laboratory trash.

Where must chuck keys and mill vise handles be kept during machining operations?

They must only be in your hand while in use or stowed away in their proper place.

What step must be taken prior to changing tooling on manual machining equipment?

Ensure that the power to the machine has been shut off.

Above what pressure level does acetylene gas become explosive?

Acetylene becomes explosive above $15\,\text{PSI}$.

What length of SMAW/stick electrodes must be saved rather than discarded?

Electrodes that are longer than $5\,\text{inches}$ should be saved.

Why must the ventilation system be turned on in the welding laboratory?

To prevent fumes and argon gas from accumulating; argon can displace oxygen and cause asphyxiation.

How far away must students stand from the furnace if they are not actively handling molten metal?

They must stay at least $15\,\text{feet}$ away.

Where is standing prohibited during pouring operations in the foundry?

No one is allowed to stand in the front direction of the furnace, regardless of distance.

What are the filling limits for a crucible and a ladle in the foundry laboratory?

A crucible must never be filled to less than $1\,\text{inch}$ from the rim (typical practice is $2\,\text{inches}$), and a ladle must not be more than $2/3$ full.

How long after pouring are castings typically shaken out for truck molds?

Typically about $15\,\text{minutes}$ after the pour.

Who is authorized to operate power shears and presses in the sheet metal laboratory?

Only the instructor/technician, or students operating under their direct supervision.

What should a student do if an injection die or component starts falling in the plastics laboratory?

Let it fall; do not attempt to catch it.

When is it safe to activate robots in the automation and robotics lab?

Only activate robots when they are within their enclosure, and always work outside of their motion envelope.

What action should be taken if an autodarkening face shield flickers or fails to darken during electric welding?

Inform the instructor immediately and switch to a non-autodarkening shield.
