Safety first — always. Colored smoke grenades are designed for consumer use and have an excellent safety record, but like any smoke-producing device, they need to be used responsibly. Here's everything you need to know about using smoke bombs safely — from ignition technique to legality, disposal, and what to do if a unit misfires.
Are Smoke Bombs Safe?
Yes. The Enola Gaye smoke grenades sold by Shutter Bombs — the EG25, WP40, WP40-D, TP40, and Twin Vent II — are specifically designed for consumer use. They are:
- Non-explosive — they produce smoke through a controlled chemical reaction, not combustion or detonation
- Non-toxic — the smoke is a non-toxic, sulphur-free formula, though you should still avoid directly inhaling large amounts (composition details are on our safety data sheets)
- Cool-burn formula — there's no open flame, but the can still gets hot during and after the burn. Hold by the base with gloves, or set it on non-flammable ground
- Built for events and photography — consumer-grade devices, not military pyrotechnics
That said, "safe" doesn't mean "zero caution required." Follow the guidelines below for a great experience every time.
Safety Note
Never use smoke grenades indoors. Indoor use can trigger fire alarms, leave permanent residue, create breathing hazards, and violate fire codes. All use must take place in open, well-ventilated outdoor areas — here's why indoor use doesn't work and what to do instead.
How to Ignite a Smoke Bomb Safely
Most "faulty" smoke bombs are actually ignition-technique problems. The pull takes roughly 5–8 pounds of force, and direction matters:
- Wire-pull models (EG25, WP40, WP40-D, Twin Vent II): grip the can firmly in one hand, hook a finger through the ring, and pull firmly to the side — never straight up. A hesitant or straight-up pull is the most common cause of misfires.
- Top-pull (TP40): the TP40 works the opposite way — pull the cap straight up. It's designed for fast, one-handed activation between takes.
- Expect brief sparks: ignition produces sparks for 1–2 seconds. Wear gloves and eye protection, keep the vent pointed away from your body, and never look down into the can.
- Immediately after ignition: either hold the can by the base or set it on a flat, non-flammable surface. The vent area generates heat for the entire burn.

Essential Safety Rules
1. Outdoor Use Only
This is the most important rule. Never use smoke bombs indoors. Indoor use can:
- Set off fire alarms and sprinkler systems
- Leave heavy residue on walls, furniture, and floors
- Create breathing hazards in enclosed spaces
- Violate fire codes and result in fines
Always use in open, well-ventilated outdoor areas.
2. Keep Away from Flammable Materials
While smoke grenades are not explosive, the chemical reaction does produce heat at the emission point. Keep smoke bombs away from:
- Dry grass, leaves, and brush
- Paper, fabric, and other combustible materials
- Gasoline, propane, and other flammable liquids
- Wooden structures and decks
Use on concrete, asphalt, gravel, or green (wet) grass when possible.
3. Don't Point the Emission Vent at People
The smoke itself is safe to be around, but the emission point where smoke exits the grenade is the hottest part. Don't point the vent directly at skin, eyes, or clothing at close range, and keep bystanders about 2 meters back from an active can.
4. Have Water Nearby
Keep a bucket of water or a garden hose accessible as a precaution. After use, you can douse the spent grenade in water to ensure it's fully extinguished before disposal.
5. Supervise Children
Smoke grenades are not toys, and purchase requires you to be 18 or older. Children should watch from a safe distance, and only adults should handle and activate smoke bombs.
6. Check Wind Conditions
Strong wind will disperse smoke quickly and may blow it in unintended directions. Light to moderate wind is ideal. Position yourself upwind of the smoke for the best experience.
Pro Tip
Wear gloves and eye protection when activating any smoke grenade. Set the unit on a flat, non-flammable surface immediately after pulling the ring — sparks occur for 1–2 seconds at ignition, and the casing heats significantly over a 90-second WP40 burn. Stored cool and dry, unused cans keep a 10+ year shelf life, so there's never a reason to rush a shoot in bad conditions.
What About Staining?
Colored smoke can leave residue on:
- Light-colored clothing — wear dark clothes or clothes you don't mind getting colored; the dye rinses out of most fabrics with soap and water
- Porous surfaces — some dye may settle on concrete or stone, though it typically washes away with rain or pressure washing
- Skin — temporary discoloration may occur but washes off easily with soap and water
- Cars — avoid using near vehicles with light-colored paint
Staining risk is concentrated within roughly 30 cm of the vent — at normal shooting distances, subjects and bystanders rarely pick up any color. Test in your planned location beforehand if staining is a concern, and read our full guide on whether smoke bombs stain clothes.
Are Smoke Bombs Legal?
Colored smoke grenades are legal to purchase and use in most US states — for the full breakdown by state, see our guide on whether smoke grenades are legal. They are classified as smoke-producing devices, not fireworks or explosives. However:
- Some cities and counties have local ordinances restricting their use
- National parks generally prohibit smoke devices outright — check our guide to smoke bombs in national parks before planning any shoot on federal land
- Some venues and event spaces have their own rules
Always check your local regulations before purchasing or using smoke bombs — our state legality and hazmat shipping page covers the common questions. When in doubt, contact your local fire department — they'll tell you exactly what's allowed in your area.
California Note
California seasonal fire ordinance restrictions actively apply during dry conditions. Always verify with your local county fire authority before any outdoor shoot — restrictions can change based on current fire danger ratings.
How Smoke Bombs Ship
Because smoke grenades are classified as pyrotechnic dangerous goods for transport, they ship via certified hazmat ground (FedEx/UPS) only — no express, overnight, or air shipping exists for these products, from anyone. Shutter Bombs ships from a Nevada warehouse to the contiguous US except Massachusetts; we can't serve Alaska, Hawaii, international addresses, or PO boxes (a street address and signature are required). Orders of $225+ ship free. The full details are in our smoke bomb shipping guide.
Proper Disposal
After a smoke grenade is fully spent:
- Wait 5 minutes after the smoke stops to ensure the reaction is complete
- Douse in water as an extra precaution
- Allow to cool completely
- Dispose of in regular trash — spent smoke grenades are not hazardous waste
Misfired units are different: never re-pull, open, or disassemble a can that failed to ignite. Submerge it in water for 48 hours before disposal — and document it first if you're filing a guarantee claim (see below).
What to Do If Something Goes Wrong
Smoke grenade won't activate: set it down on a non-flammable surface, step back, and wait at least 60 seconds — never re-pull or open it. Take a photo or video of the unit, then email hello@shutterbombs.com to claim your replacement under the 100% product guarantee. Once the claim is documented, submerge the misfire in water for 48 hours before throwing it away. More fixes in our smoke bomb troubleshooting guide.
Smoke causes eye irritation: move to fresh air immediately. Rinse eyes with clean water. The irritation should subside quickly.
Accidental fire: use water to extinguish immediately. If the fire spreads, call 911.
Skin contact with hot vent: run cool water over the affected area. Seek medical attention for burns.
The Bottom Line
Colored smoke grenades have an excellent safety record when used responsibly for photography, events, and celebrations. By following these simple guidelines — outdoor use, a firm side pull, away from flammables, adult supervision — you'll have an incredible experience every time.

Frequently Asked Questions
Are smoke bombs toxic?
No — the Enola Gaye grenades Shutter Bombs sells use a sulphur-free, non-toxic composition designed for use around photographers, models, and event guests. The smoke is not classified as a toxic substance, and at normal shooting distances bystanders face minimal exposure. That said, no smoke of any kind should be deliberately inhaled at close range, and all use should take place outdoors with adequate ventilation. People with asthma, COPD, or other respiratory sensitivities should keep extra distance from the cloud and avoid standing downwind during the burn. The WP40 burns for roughly 90 seconds and the Twin Vent II dumps its whole charge in a dense ~25-second burst, so factor wind direction into your setup to keep the cloud off anyone sensitive. Composition details are published on our safety data sheets page.
Can smoke bombs start a fire?
The risk is low but not zero, and official safety documentation is direct about it: never use near dry grass, wooden decks, or any flammable materials. Sparks are produced for 1–2 seconds at the moment of activation, and heat is generated within 1–2 cm of the smoke vents throughout the burn — about 90 seconds for a WP40, ~60 for a WP40-D or TP40, and a dense ~25-second burst for the Twin Vent II. Set the can on concrete, gravel, or bare soil rather than mulch, dead leaves, or wood. In California, seasonal fire ordinance restrictions apply in many counties during dry months — verify local rules before shooting. Wherever you are, have water immediately on hand before activating any smoke grenade.
Are smoke bombs legal in my state?
Smoke grenades are legal for adults 18 and older in most US states. They're classified as smoke-producing devices — Division 1.4G/1.4S dangerous goods for transport purposes — not fireworks, and no permit is required for use on private property in most jurisdictions. The big exceptions: national parks generally prohibit smoke devices outright, California counties apply seasonal fire restrictions during dry conditions, and some cities and venues have their own ordinances. Shutter Bombs ships certified hazmat ground (FedEx/UPS) from a Nevada warehouse to the contiguous US except Massachusetts — no Alaska, Hawaii, or international destinations. For specifics, see the state-by-state legality guide or check with your local fire department.
Can I hold a smoke bomb while it is burning?
Not bare-handed, and never near the vent. The casing heats up significantly over the course of the burn, with heat concentrated within 1–2 cm of the smoke vents. For a WP40 that means up to 90 seconds of sustained heat buildup; even the compact EG25, with its ~25-second burn, produces enough heat to cause discomfort or injury if held bare-handed. Whoever activates the device should wear gloves and eye protection, and either hold the can by the base — well away from the vent outlet — or set it on a stable, non-flammable surface immediately after pulling the ring. Bystanders should keep a 2-meter distance from an active can, and the vent should never point at anyone's body or face.
What should I do if a smoke bomb does not ignite?
First, rule out technique: wire-pull rings need a firm, decisive pull to the side (never straight up) with roughly 5–8 pounds of force. If the unit genuinely won't ignite, don't approach it immediately — keep your distance for a full 60 seconds in case of delayed ignition, and never re-pull, open, or attempt to dismantle it. Take a photo or video of the unit, then email hello@shutterbombs.com with your order number — every unit is covered by the 100% product guarantee, and you choose between store credit at 1.5× the unit price or an exact refund, processed in 1–2 business days. After the claim is documented, submerge the misfired can in water for 48 hours before discarding it in regular household waste.
Can I extinguish a smoke bomb once it's been activated?
No — once activated, the pyrotechnic composition burns through to completion and there's no mechanism to stop or pause it. Burn times run about 25 seconds for the EG25, ~60 for the WP40-D and TP40, ~90 for the WP40, and a dense ~25-second burst for the dual-vented Twin Vent II. If you need to put the grenade down mid-burn, place it immediately on a flat, non-flammable surface like concrete, dirt, or gravel and step back. Never attempt to smother, submerge, or tamper with an actively burning grenade. Once the burn is complete and the casing has cooled, douse the spent unit in water as a precaution before discarding it in regular household trash. Planning your shot setup around the burn time — see our model comparison guide — is the best way to manage timing.
