The purpose of this Amendment is to:

1. Answer Question received from Amendment 01

2. Revise MEC 22

QUESTION 9:

I think the spec was modified incorrectly.

QUESTION 3:

MEC 22 - Safety latches are frequently installed on rack washers. Is this item required for the Tunnel Washer?

RESPONSE 3:

Remove - Doors shall be equipped with spring loaded, explosion relief type safety latches that open readily when pushed from inside the chamber.

Is this actual spec change correct? It appears the wrong sentence got the strikethrough.

1. All mechanical, piping, and electrical components will be readily accessible for maintenance.
