In the context of access ladders, ANSI Type 1 and Type 2 typically refer to the duty ratings of portable ladders. Type 1 ladders are known as Heavy-Duty ladders, suitable for industrial use, with a load capacity of up to 250 lbs. Type 2 ladders, termed Medium-Duty, are more suitable for commercial and do-it-yourself applications, with a load capacity of up to 225 lbs. Type 1 ladders are generally more robust and durable compared to Type 2.

When climbing a ladder, it's imperative to face the ladder and use both hands for a secure grip. Always maintain three points of contact, such as two hands and one foot, or vice versa, to ensure stability. Wearing slip-resistant shoes is essential to prevent slips. Climb slowly and deliberately, making sure to keep your body centered between the rails to avoid tipping. Refrain from carrying items in your hands; instead, use a tool belt or hoist, and never ascend beyond the ladder's recommended safe height, typically the second-to-last rung on stepladders or third-to-last on extension ladders.
