Following Policies and Procedures
Church Safety & Security Volunteer Academy
Only be strong and very courageous, being careful to do according to all the law that Moses my servant commanded you (Joshua 1:7).
I have done according to all that you have commanded me (Deuteronomy 26:14).
...that without fail they would keep these two days according to what was written and at the time appointed every year (Esther 9:27).
But all things should be done decently and in order (1 Corinthians 14:40).
In the News:
Thankfully, procedures were followed
July 13, 2018, Dallas, Texas - An office employee opening the mail at the First Baptist Church in Dallas found a suspicious white powder in an envelope. The incident was reported to police and Dallas Fire-Rescue. The powder turned out to not be toxic, and the employee was not harmed. Since the nature of the powder was unknown, it was wise to follow the procedure: report it immediately, isolate the substance awaiting identification, and wash of any that has come in contract with the skin. 
Safeguards were not established
December 19, 2017, Fincastle, Virginia - The treasurer of a church in Botetourt County who embezzled over $99,000 was sentenced to two years in prison. The money, collected over five years' time, was from funds for assisting those in need. The treasurer was the only one with access to the account through a debit card. Contributing factors enabling the misappropriation of funds included lax bookkeeping and no clear standards for spending. 
Protocol in place
August 21, 2018, Hixson, Tennessee - A church operated school received a bomb threat on a Tuesday afternoon just after lunchtime. Immediately, the principal halted classes, evacuated the building, and alerted police. Students and staff were bused to a safe place. The church and school were credited with having emergency protocols in place, which were followed in this incident. 
Policies and Procedures Are Necessary
In the Bible texts above, we see references to God's written law, to a civil law, and to conducting church business and services in an orderly manner. In common speech, we should do God's work "by the book."
When it came to the Tabernacle, then the Temple, the "Book" had a lot to say about how they were built and furnished and how services (sacrifices, fasts, and festivals) were conducted. There were requirements and standards for the Priests and the Levites. There were protocols for how offerings were collected and distributed, and for charity. There were also procedures for handling certain illnesses.
For things to be done decently and in order in our churches, we need bylaws (or charters), policies, and procedures. Some of these should concern issues of safety and security. Members of the church safety and security team need to know these policies and procedures and follow them.
Policies and Procedures for Churches
The Sheepdog Church Security Training Bundle "Church Safety / Security Volunteer Academy, v3"  has a sample list of policies and procedures for security in a local congregation. Each item has a brief description:
- Identifying Personnel tells how to identify members of the church safety/security team with sensible suggestions which can be adopted or adapted by a local church.
- Supporting Ministry tells team members what they can do to gain support for the ministry from church members.
- Staffing guides the ministry in determining how many team members are needed to do the job.
- Volunteer Schedule covers who works where and when.
- Communication says how safety team members communicate, especially on the radio and with the head usher and greeters.
- Safes - This policy determines who has access to the safe and the conditions for that access.
- Cash/Offering Security - A "safe cash" policy which outlines procedures for handling offerings and cash (such as from sales and cafes).
- Robbery - How to prevent robberies and how to respond to one.
- Bomb Threats - What to do in case a bomb threat is received.
- Suspicious Package Threats - What you should do if you receive or find a suspicious package.
- Incident Reports - "Any time that the security team is involved in any non-routine action, an incident report should be thoroughly completed."
There is more explanation of each of these in the course. This is only a sample; there may be other policies and procedures your church may enact for the specific needs of your congregation.
Policies and procedures are guidelines which are more than suggestions. They have been formulated and adopted by the church for a reason - they are to protect the church and its members. For them to be effective, they must be followed, and this is not an option - it is a requirement.
One aspect of an investigation into any serious incident is the question of whether policies and procedures had been faithfully followed. If not, the next question is "Who did not follow them?"
For this reason, Church Safety Team members must learn the policies and procedures of their congregation and follow them. These should be available in a written form so that they can be referenced when needed. Also, team members should be notified of any changes to a policy or procedure. Failure to follow them can result in a reprimand or dismissal from the team.
