Deciding when to act on a concern about someones mental health or safety turns on two things: the immediacy of risk and the persons capacity to keep themselves safe. This guide sets out common warning signs and the types of services to contact, so the next steps are clear.
The order below reflects what matters most when time is limited: immediate risk first, then patterns that suggest escalating need, and finally signs that require safeguarding or specialist intervention. Each point stands alone so a single heading gives a usable decision rule.
How to decide what to do
First ask two simple questions: is there an immediate danger to life or limb, and can the person follow simple instructions to stay safe? If the answer to either is yes, call emergency services or an ambulance. If not, choose a crisis line or local mental-health service depending on whether the problem is acute, ongoing, or rooted in abuse or exploitation.
Common mistakes people make
People often wait for proof rather than acting on reliable signals; another frequent error is using the wrong service, for example contacting a general practitioner for an immediate suicidal crisis. Avoid both mistakes by prioritising urgency over certainty and matching the service to the problems nature: medical emergency, psychiatric crisis, safeguarding concern or addiction support.
What differs for someone new to support
Someone approaching help for the first time will generally need more active signposting and reassurance about confidentiality and options. Experienced help-seekers may already know local services and prefer telephone or online-chat support that preserves anonymity. Offer practical assistance to first-timers: find a number, explain what to expect, and if needed, stay with them while they make the call.
Suicidal thoughts or plans
Suicidal thoughts or plans
Immediate action is required when someone expresses intent, has a plan, or talks about killing themselves. These statements indicate high risk even without a specific timeline; contact emergency services or a crisis line that handles imminent suicide risk and stay with the person until help arrives if it is safe to do so.
Self-harm or recent injury
Visible cuts, burns, or other recent injuries from deliberate self-harm require medical assessment and mental-health follow-up. Treat severe injuries as medical emergencies; for non-life-threatening self-harm, contact a crisis line or community mental-health team to arrange urgent assessment and support planning.
Sudden or extreme behavioural change
Marked shifts such as severe agitation, uncontrollable panic, psychotic symptoms (hallucinations or delusions), or a sudden collapse in functioning suggest a psychiatric crisis. These signs often need urgent specialist assessment and sometimes inpatient care; choose emergency services or a mental-health crisis team depending on immediacy and local provision.
Withdrawal, hopelessness and talk of being a burden
Persistent withdrawal from friends and activities, pervasive hopelessness, or statements about being a burden point to increasing risk and worsening depression. These patterns merit prompt contact with a GP, community mental-health services or a psychosocial support line to set up ongoing care rather than only one-off reassurance.
Physical signs or disclosures of abuse
Unexplained injuries, fear around a current partner or guardian, or disclosures of sexual or physical abuse require safeguarding action. For children and vulnerable adults, contact local child-protection or adult-safeguarding services immediately; for adults at risk, an adult safeguarding team or the police may be the right first call.
Escalation of substance use
A marked increase in alcohol or drug use combined with mental-health symptoms increases the risk of overdose and self-harm. Addiction services, specialist crisis teams that work with substance misuse, or emergency services for suspected overdose are the appropriate contacts depending on immediate danger and the pattern of use.
Concerns about a child or other vulnerable person
If the person at risk is a child or a vulnerable adult who cannot protect themselves, act without delay. Contact statutory safeguarding services, the police if there is immediate danger, or a child-protection referral line for guidance on next steps. Do not promise confidentiality when a safeguarding risk exists.
Table: choosing the right helpline or service
| Service type | Best for | Typical response | Anonymity |
|---|---|---|---|
| Emergency services (police/ambulance) | Immediate life-threatening danger | Immediate dispatch of help | Low identity needed |
| Mental-health crisis line | Suicidal ideation, severe distress | Rapid triage and advice; possible referral | Often high can be anonymous |
| Local community services / GP | Non-urgent worsening or long-term needs | Appointment-based assessment | Low-to-medium personal details taken |
| Safeguarding / child-protection | Abuse or exploitation of children and adults at risk | Investigative response; statutory action possible | Low identity recorded |
| Addiction and overdose services | Overdose risk; escalating substance use | Overdose response or specialist referral | Variable often confidential |
Where to look for regional helplines
National and regional health services usually publish crisis numbers and pathways; for international context refer to the WHO mental health page for global standards and guidance. In the UK, NHS mental health crisis information sets out how to find local crisis teams and when to use emergency care.
What to do next
If the risk is immediate, call emergency services now. For urgent but not life-threatening concerns, ring a crisis line or contact the local community mental-health team. If the issue involves abuse or a child, contact the relevant safeguarding authority without delay. Wherever possible, stay with the person until professional help arrives and keep communications clear and calm.
Frequently asked questions
When should emergency services be called?
Call emergency services when someone is in immediate danger, has a plan to kill themselves, has severe injuries, or there is an active threat to life. Emergency responders are the correct choice when delay could lead to serious harm.
What is a mental-health crisis line for?
A crisis line provides rapid assessment and immediate emotional support for acute distress, suicidal thoughts or sudden psychiatric symptoms. They can advise on next steps and refer to local crisis teams or emergency services if needed.
How to act if a child is at risk?
If a child is at risk of harm, contact local child-protection or safeguarding services or the police for immediate danger. Do not promise to keep the concern secret and follow statutory reporting procedures.
