Moving Safety Tips
Dispose of flammables such as fireworks, cleaning fluids, matches, acids, chemistry sets, aerosol cans, ammunition, etc. 
Drain fuel from mowers and other machinery, and discard partly used cans of oil, paint, thinner, or other substances that might leak.
Carefully tape and place in individual waterproof bags any jars of liquid you plan to take with you.
Refillable tanks must be purged and sealed by a local propane gas dealer. Discard nonrefillable tanks. Some carriers and the military do not permit shipment of any propane tanks. Check with your moving company first.
Have rugs and draperies cleaned. Leave both wrapped when they are returned from the cleaners.
Obtain a written appraisal of antique items to verify the value. Avoid waxing or oiling wooden antiques and fine wood furniture prior to moving because some products may soften the wood, making it vulnerable to imprinting from furniture pads.
Think twice before dismantling your outside TV antennae; a new one may cost less than moving the present one.
Third-party servicing will likely be needed before moving such items as hot tubs, large-screen TVs, and some exercise equipment.
Talk to your moving company about PRE and POST move servicing of washer, dryer, refrigerator, dishwasher, grandfather clock, satellite dish, etc.
