10.7 General Environmental Controls & First Aid: Sanitation, Color Codes, Signs & Tags, Medical Services (Subparts J & K)

10.7 General Environmental Controls & First Aid: Sanitation, Color Codes, Signs & Tags, Medical Services

Two Small Subparts That Sit Under Every Inspection

Subpart J - General Environmental Controls and Subpart K - Medical and First Aid produce quiet, steady general industry citations because a compliance officer walks past their subject matter on the way to everything else. A CSHO conducting a machine guarding inspection still notices a blocked eyewash, a missing "Not an Exit" sign, or a lunchroom inside a lead-exposure area.

Remember the map: Subpart J also contains the two heavyweight standards this guide covers in their own chapters - 1910.146 Permit-Required Confined Spaces and 1910.147 Lockout/Tagout. The rest of Subpart J is 1910.141 Sanitation, 1910.142 Temporary labor camps, 1910.144 Safety color code, and 1910.145 Signs and tags. Medical services and first aid is 1910.151 in Subpart K, not Subpart J - a favorite citation-location question.

Sanitation (1910.141)

Housekeeping and Waste (1910.141(a))

All places of employment must be kept clean to the extent the nature of the work allows. Waste receptacles used for putrescible solid or liquid waste must be constructed so that they do not leak and can be thoroughly cleaned and maintained in a sanitary condition, and must be equipped with a solid, tight-fitting cover unless sanitary conditions can be maintained without one (1910.141(a)(4)(i)). Every enclosed workplace must be constructed, equipped, and maintained to prevent the entrance or harborage of rodents, insects, and other vermin, and where an infestation is detected an effective extermination program must be instituted (1910.141(a)(5)).

Water (1910.141(b))

Potable water must be provided in all places of employment for drinking, washing of the person, cooking, washing of foods, and washing of cooking and eating utensils. Two prohibitions carry directly onto the exam:

• The common drinking cup and other common utensils are prohibited (1910.141(b)(1)(vi)).
• Non-potable water may be supplied only for cleaning work premises other than food-processing and preparation areas and personal service rooms, and outlets for non-potable water must be posted to indicate the water is unsafe and must not be used for drinking, washing, cooking, or washing of food (1910.141(b)(2)).

Toilet Facilities (1910.141(c)) - Table J-1

Separate toilet facilities must be provided for each sex, in accordance with Table J-1:

Where toilet rooms will be occupied by no more than one person at a time, can be locked from the inside, and contain at least one water closet, separate rooms for each sex need not be provided. Each water closet must occupy a separate compartment with a door and walls or partitions between fixtures sufficiently high to assure privacy.

Washing Facilities, Change Rooms, and Eating Areas (1910.141(d), (e), (g))

• Lavatories must be made available in all places of employment, with hot and cold running water, or tepid running water, hand soap or similar cleansing agent, and individual hand towels, clean sections of continuous cloth toweling, warm air blowers, or other suitable means of drying (1910.141(d)(2)).
• Where employees are required to wear protective clothing because of possible contamination with toxic materials, change rooms with storage facilities for street clothes and separate storage for protective clothing must be provided (1910.141(e)).
• No employee may be allowed to consume food or beverages in a toilet room, nor in any area exposed to a toxic material (1910.141(g)(2)). This is the standard behind the classic finding of a coffee pot on the bench in a battery-manufacturing or plating area, and it interlocks with the lead standard's separate lunchroom requirement in 1910.1025(i)(4).

Safety Color Code for Marking Physical Hazards (1910.144)

Two colors are assigned by regulation, and the exam asks which is which:

That short list is the entire regulatory color code. Green for safety equipment, blue for information, and orange for exposed machine parts come from the referenced ANSI consensus standard and general practice, not from the text of 1910.144.

Accident Prevention Signs and Tags (1910.145)

The Three Sign Classifications

Accident Prevention Tags (1910.145(f))

Tags are a temporary means of warning about a hazardous condition, defective equipment, or radiation hazard. They are not a substitute for engineering controls, and once the hazard is eliminated the tag comes off.

Every tag must contain a signal word ("Danger," "Caution," "Warning," "Biological Hazard," or "BIOHAZARD") and a major message stating the specific hazardous condition or the instruction to be communicated. The signal word must be readable at a minimum distance of five feet (1.52 m) or such greater distance as warranted by the hazard, and employees must be informed of the meaning of the tags used and the special precautions they require.

Medical Services and First Aid (1910.151, Subpart K)

Three short paragraphs, each of them a live citation:

• 1910.151(a): the employer must ensure the ready availability of medical personnel for advice and consultation on matters of plant health.
• 1910.151(b): in the absence of an infirmary, clinic, or hospital in near proximity to the workplace that is used for the treatment of all injured employees, a person or persons must be adequately trained to render first aid, and adequate first aid supplies must be readily available. OSHA's enforcement guidance treats "near proximity" as roughly 3 to 4 minutes for life-threatening injuries such as severe bleeding, and up to about 15 minutes for workplaces without such hazards. A remote plant with no trained responder and a 20-minute ambulance run is the classic violation.
• 1910.151(c): "Where the eyes or body of any person may be exposed to injurious corrosive materials, suitable facilities for quick drenching or flushing of the eyes and body shall be provided within the work area for immediate emergency use."

THE ANSI Z358.1 NUANCE: The familiar figures - a flushing station reachable within 10 seconds of travel (about 55 feet on an unobstructed path), tepid water, and a 15-minute continuous flush - come from the consensus standard ANSI/ISEA Z358.1. OSHA has not incorporated Z358.1 by reference into 1910.151(c). It cites Z358.1 in letters of interpretation as evidence of what "suitable" and "within the work area" mean, and can reach a grossly inadequate station under Section 5(a)(1). Know both the regulatory text and the fact that the numbers are consensus-derived, because exam distractors are built on exactly that gap.
