Training/safety programs for ministering to at-risk population?

Our church is in the planning stages of forming a non-profit organization to minister to homeless in our community. We will take up residence at a local motel. We need to formulate a training program for our volunteers. We also need to develop a safety policies. Not wanting to reinvent the wheel, does anyone have access to share an existing program fir either area with us? We would use as a reference and tailor to our specific ministry. Thanks!
