Kentucky Crew Shower and Toilet Ratios Under 803 KAR and OSHA Sanitation Rules
Which Kentucky regulations pull in OSHA's sanitation rules, and how the ratios become a stall count.
Key points
- Kentucky runs its own OSH program; 803 KAR 2:309 and 803 KAR 2:403 adopt the federal sanitation rules.
- Where showers are required, plan one for each 10 employees of each sex.
- Construction: one toilet for up to 20 workers, then 1 seat and 1 urinal per 40.
Kentucky is a state-plan state: workplace safety here is enforced under Kentucky's own regulations in Title 803 of the Kentucky Administrative Regulations, not directly by federal OSHA. For sanitation, the state rules point straight back to the federal text, so the numbers a Kentucky superintendent works with are OSHA's.
The two Kentucky regulations to know
- 803 KAR 2:309 says general industry “shall comply with 29 C.F.R. 1910, Subpart J, General Environmental Controls,” and that subpart contains 1910.141, the sanitation rule.
- 803 KAR 2:403 requires the construction industry to comply with 29 C.F.R. 1926.50 through 1926.66, a range that covers 1926.51, construction sanitation.
The numbers they bring in
- Showers, where a standard requires them: “One shower shall be provided for each 10 employees of each sex, or numerical fraction thereof,” fed with hot and cold water (1910.141(d)(3); the construction rule, 1926.51(f)(4), uses the same ratio).
- Construction toilets (Table D-1): at least one for 20 or fewer workers; 1 toilet seat and 1 urinal per 40 workers for 20 or more; per 50 for 200 or more.
- General industry toilets (Table J-1): 1 water closet for 1 to 15 employees, 2 for 16 to 35, 3 for 36 to 55, rising to 6 for 111 to 150.
Turning a ratio into a trailer
Count each sex separately and round up. A shutdown crew of 34 men and 9 women on the same shift needs four showers for the men and one for the women: five stalls. Size to the busiest hour, because a shift change sends everyone to the showers at once.
- Up to 3 stalls: the 13ft Luxury Shower-Restroom Combination Trailer (3 Individual Stalls), from $2,495 / month, a shower and toilet behind each door.
- 5 stalls: the 20ft Shower Container (5 Individual Stalls), from $3,995 / month, showers only, so add a restroom trailer.
- 6 to 10 stalls: the 22ft Luxury Shower-Restroom Combination Trailer (6 Individual Stalls) or the 30ft Luxury Shower-Restroom Combination Trailer (10 Individual Stalls).
