Retail and grocery stores are among the busiest public spaces in any community. A typical store sees hundreds, sometimes thousands, of people a day — shoppers of every age, including seniors and young children. With that much foot traffic, medical emergencies are not a question of if but when: a customer collapses near the registers, someone chokes on a sample, a shopper trips on a wet floor, or a staff member is cut stocking shelves.

This guide helps store owners, managers, and staff prepare for both customer and employee emergencies — so that when something happens on the shop floor, your team responds with confidence.

When a Customer Collapses

The most serious in-store emergency is a customer who collapses. Because stores serve so many people, including older adults, sudden cardiac arrest does happen on shop floors — and a prepared store is one of the best places to survive it.

Choking

Food samples, café areas, and in-store dining mean choking can happen. If a customer can cough, speak, or breathe, encourage them to keep coughing — a forceful cough is the most effective way to clear a partial blockage. If they cannot breathe, speak, or cough and are clutching their throat, the airway is completely blocked and you must act at once.

For an adult or a child over one year, the current Canadian Red Cross and Heart & Stroke sequence (aligned with AHA/ERC 2025 and ILCOR) is to lead with back blows:

1. Give 5 firm back blows between the shoulder blades with the heel of your hand.
2. If that doesn’t clear it, give 5 abdominal thrusts (quick, forceful upward thrusts just above the navel).
3. Alternate 5 back blows and 5 abdominal thrusts until the object is expelled or the person becomes unresponsive.

For an infant under one year, give 5 back blows and 5 chest thrusts (using the heel of one hand on the lower half of the breastbone) — never abdominal thrusts. If the person becomes unresponsive, lower them to the floor, call 911, and begin CPR.

Slips, Trips, and Falls

Wet floors, spills, cluttered aisles, and entrance mats make falls one of the most common store incidents for both customers and staff. For a fall:

• Do not rush to move the person — check for injuries first
• If they may have hurt their head, neck, or back, keep them still and call 911
• Control any bleeding with direct pressure and a clean dressing
• Apply a wrapped cold pack to bruises or possible sprains
• For a possible fracture (deformity, severe pain, inability to move or bear weight), support the limb and arrange medical care
• Document the incident and address the hazard (clean the spill, post a sign) to prevent the next one

Common Staff Injuries

Behind the scenes, retail and grocery work carries its own risks:

• Back strains from lifting and stocking — train staff in safe lifting and use equipment for heavy loads
• Cuts from box cutters, broken glass, and packaging — handle blades carefully and dress wounds promptly (see our wound care guide)
• Crush injuries from falling stock, pallets, or equipment
• Burns or cold injuries in bakery, deli, and freezer areas
• Slips in back rooms and loading docks

Medical Events: Seizures, Diabetes, Allergies

With so many people in store, staff may encounter a customer having a seizure, a diabetic emergency, or an allergic reaction. Quick reference:

• Seizure: protect from injury, don’t restrain or put anything in the mouth, turn on the side after, call 911 if it lasts over 5 minutes, is a first-time seizure, or another follows. See our seizure guide.
• Low blood sugar: if the person is conscious and able to swallow, give 15–20 g of fast-acting sugar (about 50–100 ml of juice or regular, non-diet soda), then recheck in about 15 minutes and repeat if still unwell (Diabetes Canada “Rule of 15”). See our diabetic emergencies guide.
• Severe allergic reaction: help the person use their epinephrine auto-injector right away and call 911; if there is no improvement, a second dose can be given after about 5 minutes. See our anaphylaxis guide.

Your Store’s Emergency Plan

• Trained first aiders on every shift — at least the legal minimum, ideally more across departments
• Accessible, stocked first aid kits at known locations (registers, back room, staff area)
• An AED in a signed, central, reachable spot, with staff trained to use it
• A clear call procedure — who calls 911, the store’s exact address posted, and who directs paramedics in
• Incident reporting to document events and fix hazards
• Periodic refreshers and drills so staff stay sharp

Train Your Team Efficiently

Retail has high staff turnover and tight schedules, so efficient, practical training matters. A Life Safe first aid and CPR course gives your team hands-on skills for the emergencies stores actually see, and our on-site training can certify staff at your location, minimizing disruption.
