Lab safety - Long vs. Short Sleeves on Lab Coats
At my university we are all required to wear long sleeve coats in chemistry labs. It simply protects more of your body compared to a short sleeve coat.
As an example, in one of my labs a guy had his sleeves rolled up and then he decided to rest his forearm on the fumehood while he was working with sulfuric acid. It turned out he spilled some acid earlier so he ended up with a burn all along his arm. This could also happen if pouring chemicals - if you spill some, your arm won't be covered.
Long sleeves are also important when handling liquid nitrogen with cryogenic gloves. You need to have your sleeves going over the ends of the gloves, to prevent any liquid nitrogen falling into the gloves where it can't evaporate easily off the skin and could cause burns.
I suppose one hazard with long sleeves is that spilling a chemical on your hands could cause it to roll down your sleeves and increase the contact time of the chemical with your skin as you then need to take the time to remove your lab coat before you wash your arm, but ideally your coat will be tight at the cuffs to minimise this risk.

Considering the coats purpose as personal protective equipment (PPE) is to reduce or eliminate the potential or risk of exposure to materials then the long sleeve coat would be the correct PPE to wear in a chemistry laboratory along with extra PPE which should have been assessed prior to performing the procedure.
Even in a microbiology or molecular biology lab, where a lot of the solutions might not seem harmful, the cellular material in suspension is classed as a bio hazard, which the long sleeve will provide better protection.
Hazardous chemicals are still commonly used in these labs, too, and will most likely be present whether you using them or not. It's not just for chemical exposure either also for general protection.

To add to @Joel's excellent answer, one of the reasons that short-sleeved lab coats are even used at all, is according to a HealthCare Business and Technology article Short-sleeved lab coats just as germy as long-sleeved, due to
Some hospitals (and individual health pros) have switched to short-sleeved lab coats under the belief that the reduction in the amount of fabric would also lead to a drop in the amount of bacteria picked up during the day — and potentially passed on to patients and co-workers.
no statistically significant difference between the amounts of the bacteria on the long- or short-sleeve coats.
So, asides from the protection to your arms from chemical or biological splashes, glass splinter etc, there is no additional protection from the spread or pickup of bacteria with short sleeve lab coats.

The short sleeve has no place in a chemistry lab.
