Safety, Inspection, and Customer Communication
What the exam tests
This domain tests documentation, risk recognition, and honest expectations. The exam expects you to inspect before you clean, test before you commit, and explain what cleaning can and cannot fix.
Inspection and documentation
Record fiber, construction, cleaning code (W, S, WS, X, or O for solvent-only), soil type, and pre-existing conditions: sun fading, pile crush, wear, pet damage, urine rings, dye bleed, shrinkage, and previous cleaning damage. Photograph and note them on the work order before cleaning. Test colorfastness and shrinkage on a hidden area with the actual chemistry and method.
Safety essentials
Read the SDS before use; wear gloves and eye protection; ventilate solvent and bleach use; use GFCI protection on portable equipment; keep cords out of walkways; never mix chlorine bleach with ammonia or acid; treat hot-water lines and solvent vapors as hazards; control slip and fall risk from wet floors.
Communication
Use plain language: 'This stain is likely to lighten, not disappear.' Explain that some conditions become permanent (sun fading, dye loss, burns, urine damage to backing), and that cleaning can reveal pre-existing wear. Get written approval for the method and for any limitation.
Worked example
A sofa has a faded stripe where a cushion sat in sunlight. You note it on the inspection form, photograph it, and tell the customer before cleaning: 'The fade is dye loss, not soil; cleaning will not restore it, and the contrast may look stronger when surrounding soil is removed.' The customer signs, and you clean with a mild method.
Traps
Promising complete stain removal; not documenting pre-existing damage; cleaning an X code; skipping a test because the fabric looks like cotton; using a customer's unknown product; discussing liability only after a problem.
