Caustic Cleaners Can Burn Without an Immediate Warning

Understand the hazard

Focus: Alkaline cleaning.

Alkaline cleaners remove oils and soils before plating, but they can also injure skin and eyes. A wet cuff, soaked glove, or small splash can keep the cleaner against the body. Lack of immediate pain does not mean the exposure is harmless. Hot cleaner adds a thermal hazard to the chemical hazard.

Use the controls

Inspect splash protection before opening a cleaner container or servicing the tank. Confirm glove and clothing compatibility for the actual cleaner and temperature. Keep sleeves, glove cuffs, and apron placement consistent with the assessed task so liquid is not trapped against skin. Use tools that allow the job to be done without reaching into the solution.

Stop, report, and verify

Report suspected contact promptly and follow the product-specific first-aid and site emergency procedure. Use emergency flushing immediately when indicated; do not delay while looking for a supervisor. Remove contaminated items as trained while avoiding further exposure. Do not apply a neutralizing chemical to the body. Arrange medical evaluation through the response plan.

Discuss with the team

A worker notices cleaner inside a glove but wants to finish the rack before changing.

Question: What should the worker do first?
Answer guidance: Stop the exposure and begin the required first-aid response without waiting to finish production.

Question: Should a worker wait for pain before responding to cleaner contact?
Answer guidance: No. Suspected contact needs prompt product-specific first aid and reporting.

Prepare, practice, and follow up

Leader preparation: Bring the current instruction for alkaline cleaning, the relevant site checklist, and clean demonstration materials. Confirm the assigned lead and local stop-work response before presenting.

Activity: Identify the nearest emergency flushing equipment and demonstrate the safe response using a dry practice scenario.

Follow-up: Observe the next applicable task and verify this practice: identify the nearest emergency flushing equipment and demonstrate the safe response using a dry practice scenario. Record any gap, responsible person, and completion check before repeating the task.
