Construction is a dangerous job as well. You can be hit by falling things, there can be heavy equipment failures, you can fall off the buildings if you're not sufficiently harnessed. Electricians too - there's a chance, however small, of receiving a lethal shock. Delivery drivers could get killed in car accidents, it happens every day (car accidents, not specifically involving pizza drivers but given they're on the road more often it's a statistically higher probability for them)
