For most people with latex allergies, the biggest problem is latex particles that get into the air - like latex gloves or balloons that shed latex particles during normal use.
Things like carpeting, tires and latex coatings on handrails, etc. don't tend to shed latex particles during normal use, so are not as much of a problem for most people with latex allergies. Some people have allergy problems if they get into direct contact with those items, but may not have any problem with them being in the environment. That is very different than gloves and balloons.
It would be a "reasonable accomidation" for health care providers and businesses to avoid using latex gloves and balloons. There are alternatives available that can be substituted (and for balloons, there are additional reasons - like animal/bird hazards - to avoid using them).
