24 Nail Gun Injury Statistics for Home Projects (2026)
Cited data on how many people are hurt by nail guns, who gets hurt, what the injuries are and how trigger type changes the risk.
US emergency departments treated about 37,000 nail gun injuries a year from 2001 to 2005, according to the CDC. About 40% of those patients were consumers hurt outside of paid work, such as homeowners on a deck or trim job. NIOSH calls nail guns a leading cause of injury among residential carpenters. The 24 statistics below cover how many people get hurt, who they are, what the injuries look like and how trigger type changes the risk. For trim, shelving and built-ins, book a vetted local carpenter instead.
Figures come from the CDC's 2007 Morbidity and Mortality Weekly Report on nail gun injuries, NIOSH's nail gun safety pages, and peer-reviewed studies of carpenters by Duke University and NIOSH researchers, as listed on PubMed. Hospital counts use the US National Electronic Injury Surveillance System (NEISS) sample. We found no Canadian national data on nail gun injuries, so these are US figures. All sources were checked on November 1, 2026.

How many people are hurt by nail guns each year?
Tens of thousands. US emergency departments treated about 37,000 nail gun injuries a year from 2001 to 2005, and about 4 in 10 of those patients were not at work. Consumer injuries rose about 200% after 1991, as cheap nail guns and air compressors reached home hardware stores. Later research put the yearly count near 25,000.
1. About 37,000 ER visits a year
From 2001 to 2005, an average of about 37,000 patients a year were treated in US emergency departments for nail gun injuries (CDC). That is about 100 a day.
2. 40% of injuries were among consumers
About 40% of those injuries, or 14,800 a year, happened to consumers outside of paid work. Yearly consumer counts ranged from 13,400 to 16,200 over the five years (CDC).
3. Workers averaged 22,200 injuries a year
Work-related nail gun injuries ranged from 19,300 to 28,600 a year from 2001 to 2005, with an average of 22,200 (CDC).
4. Consumer injuries tripled from 1991 to 2005
Consumer nail gun injuries in 2005 were about three times the 1991 count of 4,200, a rise of about 200%. The CDC links the rise to cheap nail guns and compressors reaching home hardware stores in the 1990s (CDC).
5. Worker injuries jumped 39% in 2005
The estimated number of worker nail gun injuries rose 39% from 2004 to 2005. The CDC said the rise was not statistically significant but called for close monitoring (CDC).
6. About 25,000 ER-treated injuries a year from 2006 to 2011
A later study of NEISS data estimated about 25,000 ER-treated nail gun injuries a year from 2006 to 2011 (Lipscomb and Schoenfisch, 2015). NIOSH says construction nail gun injuries appear to have declined as residential building fell after 2006 (NIOSH).

Who gets hurt by nail guns?
Mostly men, and mostly people new to the tool. In 2005, 96% of injured consumers and 98% of injured workers were men. Among apprentice carpenters, those with less than a year on the job and those with no nail gun training faced close to three times the risk of more experienced, trained workers.
7. 96% of injured consumers were men
In 2005, about 12,800 (96%) of 13,400 injured consumers and 28,000 (98%) of 28,600 injured workers were men (CDC).
8. Injured consumers had a median age of 35
Injured workers had a median age of 27, and injured consumers a median age of 35 (CDC).
9. 60% of nail gun ER visits are work-related
NIOSH says nail guns cause about 37,000 emergency room visits a year, and about 60% of those are work-related. It calls nail guns a leading cause of injury among residential carpenters (NIOSH).
10. 45% of apprentice carpenters had a nail gun injury
In a survey of 772 apprentice carpenters, 45% said they had been injured by a nail gun (Lipscomb et al., 2006).
11. Apprentices were hurt at 3 times the journeyman rate
Among residential carpenters followed in active injury surveillance, apprentices had 3.7 nail gun injuries per 200,000 hours worked, against 1.2 for journeymen (Lipscomb et al., 2003).
12. Under a year of experience meant 2.7 times the risk
Apprentices with less than a year of experience had 2.7 times the nail gun injury risk of those with more than five years (Lipscomb et al., 2006).
13. No training meant 2.9 times the risk
Apprentices with no training in tool use had 2.9 times the injury risk, the highest of any factor studied (Lipscomb et al., 2006). NIOSH also says untrained workers are more likely to be injured (NIOSH).
What kinds of injuries do nail guns cause?
Mostly puncture wounds to the hands and fingers. In the CDC data, 87% of injuries were punctures or wounds with a nail or other object still in the body. Upper limbs made up three quarters of consumer injuries. Most patients were treated and sent home, but about 1,500 workers were admitted to hospital in 2005.
14. 87% were puncture or embedded-object wounds
For both consumers and workers, 87% of nail gun injuries were puncture wounds or open wounds with a retained nail or other object (CDC).
15. 75% of consumer injuries hit the arms and hands
Upper limbs, mostly hands and fingers, made up 75% of consumer and 66% of worker nail gun injuries in 2005 (CDC).
16. 24% of worker injuries hit the legs and feet
Lower limbs made up 17% of consumer injuries and 24% of worker injuries (CDC).
Source: CDC, MMWR 56(14), 2007.
17. About 4% of worker injuries were broken bones
About 4% of worker nail gun injuries led to fractures. The CDC flags this figure as possibly unstable because the sample was small (CDC).
18. 1,500 workers were hospitalized in 2005
About 1,500 workers were admitted to hospital for nail gun injuries in 2005. Cases included nails in the trunk, head, joints or bones, and infected punctures (CDC).
19. 94% were treated and released
Most patients went home the same day: 12,600 consumers and 26,900 workers (94% of each group) were treated and released from emergency departments in 2005 (CDC).
Does the type of nail gun trigger matter?
Yes, a lot. A contact (bump) trigger fires each time the nose touches wood while the trigger is held. A sequential trigger needs the nose pressed first, then the trigger pulled for each nail. NIOSH says the contact trigger doubles injury risk, and a timed test found the sequential trigger costs very little time.
20. Contact triggers carry twice the injury risk
NIOSH says the risk of a nail gun injury is twice as high with a contact trigger as with a sequential trigger (NIOSH). The apprentice study found the same 2-to-1 gap (Lipscomb et al., 2006).
21. 65% to 69% of contact-trigger injuries were likely preventable
Injury surveillance in residential construction found about 65% to 69% of injuries from contact-trigger tools could likely have been prevented with a sequential trigger (CDC).
22. Over 70% of injuries came during through-nailing or toe-nailing
In carpenter surveillance, nail guns were involved in 14% of all injuries studied, and 90% of those were struck-by injuries. Over 70% happened while through-nailing, such as studs, trusses or joists, or toe-nailing at an angle, rather than flat nailing for sheathing (Lipscomb et al., 2003).
23. A sequential trigger added under 1% to the workday
In a test where ten journeymen carpenters each built a yard shed twice, the sequential trigger added a mean of 10 minutes of nailing. That was 10% of the 97 minutes spent nailing but only 0.77% of the 1,298 total minutes per shed, with no difference in nail count or placement (Lipscomb et al., 2008).
24. Injury rates fell 55% after training and trigger changes
Among union apprentice carpenters, nail gun injury rates in 2008 were 55% below the 2005 baseline, with early training and more use of sequential triggers. Rates stayed about twice as high with contact triggers (Lipscomb et al., 2010).
Source: Lipscomb et al., Public Health Reports, 2008. The 99.23% share is the remainder of the 1,298 mean minutes to build each shed.
What this means for homeowners
- Check the trigger. If you own or rent a nail gun, use a sequential trigger. The contact trigger doubles the injury risk.
- Get trained first. No training in tool use meant 2.9 times the risk for apprentices, and the CDC notes that consumers do not usually get tool training.
- Weigh DIY honestly. Our table saw injury statistics and ladder safety statistics show where home projects go wrong, and our carpenter cost guide shows what hiring out costs.
- Know the trade. Our carpenter statistics cover Ontario wages, training and job outlook.

Frequently Asked Questions
How many people are injured by nail guns each year?
About 37,000 a year in the US. That is the yearly average of nail gun injuries treated in emergency departments from 2001 to 2005, the CDC reports. About 40% (14,800 a year) were consumers hurt outside of paid work, and the rest were workers.
Are DIY users hurt by nail guns as often as pros?
Consumers made up about 40% of ER-treated nail gun injuries from 2001 to 2005, the CDC says. Consumer injuries in 2005 were about three times the 1991 level, a rise of about 200%, likely because cheap nail guns and compressors reached hardware stores in the 1990s.
Which nail gun trigger is safest?
The full sequential trigger. NIOSH says the risk of injury is twice as high with a contact (bump) trigger. CDC-cited research found 65% to 69% of contact-trigger injuries could likely be prevented with a sequential trigger.
What body parts do nail guns injure most?
Hands and fingers. Upper limbs, mostly hands and fingers, made up 75% of consumer and 66% of worker nail gun injuries in 2005, the CDC says. Legs and feet came next, at 17% of consumer and 24% of worker injuries.
Should I hire a carpenter instead of using a nail gun myself?
For framing, decks, trim or built-ins, a pro is often the safer choice. Research on apprentice carpenters found those with under a year in the trade had 2.7 times the injury risk of those with over five years.
