§ 655.304 Standards for mobile housing. ( a ) *Use of mobile housing.* An employer employing workers engaged in animal shearing or custom combining under this section and §§ 655.301 through 655.303 may use a mobile unit, camper, or other similar mobile housing unit that complies with all of the following standards, except as provided in paragraph (a)(1) or (2) of this section: ( 1 ) In situations where the mobile housing unit will be located on the range (as defined in § 655.201) to enable work to be performed on the range, and where providing housing that meets each of the standards for mobile housing in this section is not feasible, an employer may request a variance from the particular mobile housing standard(s) with which compliance is not feasible. The CO will specify the locations, dates, and specific variances, if approved. The following conditions must be satisfied for an employer to obtain a variance: ( i ) The employer seeks the variance at the time it submits its *Application for Temporary Employment Certification;*
( ii ) The employer identifies the particular mobile housing standard(s), and attests that compliance with the standard(s) is not feasible;
( iii ) The employer identifies the location(s) in which the particular mobile housing standard(s) cannot be met;
( iv ) The employer identifies the anticipated dates that the mobile housing unit will be in those location(s);
( v ) The employer identifies the corresponding range housing standard(s) in § 655.235 that will be met instead, and attests that it will comply with such standard(s);
( vi ) The employer attests to the reason why the particular mobile housing(s) standard cannot be met; and,
( vii ) The CO approves the variance.
( 2 ) A Canadian employer performing custom combining operations in the United States whose mobile housing unit is located in Canada when not in use must have the housing unit inspected and approved by an authorized representative of the Federal or provincial government of Canada, in accordance with inspection procedures and applicable standards for such housing under Canadian law or regulation.
( b ) *Compliance with mobile housing standards.* The employer may comply with the standards for mobile housing in this section in one of two ways: ( 1 ) The employer may provide a mobile housing unit that complies with all applicable standards; or
( 2 ) The employer may provide a mobile housing unit and supplemental facilities (e.g., located at a fixed housing site) if workers are afforded access to all facilities contained in these standards.
( c ) *Housing site.* ( 1 ) Mobile housing sites must be well drained and free from depressions where water may stagnate. They shall be located where the disposal of sewage is provided in a manner that neither creates, nor is likely to create, a nuisance or a hazard to health.

( 3 ) Each housing unit must have at least one window or a skylight that can be opened directly to the outdoors.
( g ) *Heating.* ( 1 ) Where the climate in which the housing will be used is such that the safety and health of a worker requires heated living quarters, all such quarters must have properly installed operable heating equipment that supplies adequate heat. Where the climate in which the housing will be used is mild and the low temperature for any day in which the housing will be used is not reasonably expected to drop below 50 degrees Fahrenheit, no separate heating equipment is required as long as proper protective clothing and bedding are made available, free of charge or deposit charge, to the workers.
