Thank you for your enquiry to the BRC Global Standards team.
Regarding 6.5.9, the interpretation guideline states:
Self-care laundry
“Home laundering may be the simplest option for many companies; however, this needs to be controlled by wrien instructions to staff that include how garments are to be washed (temperature, detergent, specifying items not to be washed together, and drying instructions). Employees must be provided with a suitable means to safely transport garments from home to the workplace (sealable plastic bags or similar).
“There must be a defined responsibility within the company for monitoring the effectiveness of the system. This is typically achieved by visual inspection. There must also be a procedure and system for effectively dealing with any case where employees are unable to do the laundry themselves, either through lack of diligence or through lack of facilities. This system must be capable of being brought into immediate effect once a problem has been identified.”
Ultimately, the intention is to ensure that the clothing worn by production staff does not pose a hazard to the product, echoing the statement of intent for 6.5, that protective clothing is to protect the product from contamination.
