Forklifts. Move stuff. Just be careful.
Forklifts are marvels when it comes to moving stuff. Big stuff, small stuff, lots of stuff. Boy can forklifts move stuff. Forklifts come in all sizes, from small to huge. But forklifts need be operated by well trained operators and with great care.
OSHA 29 CFR 1910.178 (l) outlines the topics that forklift training must cover. Some of the big safety issues with forklift is turning over (improper terrain/slopes or unbalance load placement on the forks). An potential hazard is the forklifts can turn on a dime, and people and property can be damaged/injured if in the travel path of a forklift is not clear.
Always use care when operating a forklift. They can move stuff quickly for you. Just use great care when operating a forklift.
