Basic universal precautions for surfaces that should be used at each harm reduction services sites include:

• All surfaces touched by supplies should be wiped down with a broad-spectrum antimicrobial surface cleaner at the beginning and end of each shift.
• Harm reduction staff or volunteers should wipe down all surfaces used by more than one person, including pens, clipboards, chairs, desks, cabinet fronts, floors, doors, steering wheels, and so on. This should be done regularly/at least once per month with a broad spectrum anti-microbial surface cleaner.
